Product Type / Packaging
   PSK Modulator Type       
   Your choices are...         
   BPSK       A BPSK (Bi-phase Shift Key) modulator modulates an input signal by 0º and 180º phase shifts. 
   QPSK       A QPSK (Quadrature Phase Shift Key, or Quadraphase Shift Key) modulator modulates an input signals by 0º, 90º, 180º, and 270º phase shifts. 
   Other       Other, not listed, PSK modulators.

   Your choices are...         
   Surface Mount Technology (SMT)       Surface mount technology (SMT) adds components to a printed circuit board (PCB) by soldering component leads or terminals to the top surface of the board. SMT components have a flat surface that is soldered to a flat pad on the face of the PCB. Typically, the PCB pad is coated with a paste-like formulation of solder and flux. With careful placement, SMT components on solder paste remain in position until elevated temperatures, usually from an infrared oven, melt the paste and solder the component leads to the PCB pads.   Industry-standard pick-and-place equipment can mount SMT components quickly, accurately, and cost-effectively. SMT is a widely used alternative to mounting processes that insert pins or terminals through holes and solder leads into place on the opposite side of the board. 
   Flat Pack (FPAK)       Flat pack (FPAK).  
   Through Hole Technology (THT)       Through hole technology (THT) mounts components on a printed circuit board (PCB) by inserting component leads through holes in the board and then soldering the leads in place on the opposite side of the board. 
   Connectorized       Connectorized devices attach with coaxial or other types of connectors. 
   Waveguide Assembly       Waveguide assemblies are used in microwave waveguide systems. They consist of a hollow metallic conductor with a rectangular, elliptical, or circular cross-section. Some conductors contain solid or gaseous dielectric materials.  
   Other       Other unlisted package types.

   RF Connector       
   Your choices are...         
   BNC       Bayonet Neil-Concelman (BNC) connectors were designed for military applications, but are used widely in video and RF applications to 2 GHz. BNC connectors have a slotted outer conductor and a plastic dielectric that causes increasing losses at higher frequencies. BNC connectors are usable above 4 GHz as long as the slots radiate signals; however, these devices may not be mechanically stable to 10 GHz. Both 50Omega: Ohms  and 75Omega: Ohms BNC connectors are available. BNC connectors are also known as bayonet navy connectors or baby Neil connectors. 
   MCX       Miniature coaxial (MCX) connectors provide broadband capability through 6 GHz and are used in applications where weight and physical space are limited. They provide good electrical performance and are used to address the rapid implementation of the U.S. digital cellular PCN infrastructure. MCX connectors are also used in global positioning systems (GPS) and wireless LAN  (WLAN) applications. 
   Mini-UHF       Mini-UHF connectors are a miniature version of the original UHF connector. They feature a threaded coupling mechanism for reliable mating. Mini-UHF connectors are designed for use in cellular mobile telephone systems where size, weight and cost are critical. With crimp cable termination for low installation costs, these connectors provide excellent RF performance in applications through 2.5 GHz. 
   MMCX       Micro-miniature coaxial (MMCX) connectors are smaller than MCX connectors and feature a more robust interface for greater durability. They are ideal for high volume, wireless SMT or PCMCIA applications in cellular base stations, cellular phones and personal communicators. MMCX connectors are also used in global positioning systems and wireless LAN (WLAN) applications. 
   SMA       Subminiature-A (SMA) connectors are intended for use on semi-rigid cables in components. They directly interface the cable dielectric without air gaps.  They are not intended for permanent connections. 
   SMB       Subminiature-N (SMB) connectors are snap-mount connectors that are available either in 50Omega: Ohms or 75Omega: Ohms impedances.  They are used for frequencies from DC to 4GHz. 
   SMP       Subminiature P (SMP) connectors are rated to 40 GHz and, depending on detent type, can withstand from 100 to 1,000 interconnect cycles. 
   TNC       Threaded Neil-Concelman (TNC) connectors are similar in size to BNC connectors but feature a threaded coupling nut for applications that require performance to 11 GHz. TNC connectors are durable, reliable devices that are widely used in the cellular and mobile communication industry for equipment cabling and antenna interfaces. 
   Type F       Type F connectors have a screw-type coupling and frequency range up to 1.5 GHz. Applications include CATV, TV, and antennas. 
   Type N       Type N connectors include an integrated gasket to protect against environmental ingress and create an air gap between the center and the outer conductor. They primarily have 50Omega: Ohms impedance, but 75Omega: Ohms versions for CATV, are available. 
   UHF       Ultra high frequency (UHF) connectors are economical, all-purpose connectors designed with non-constant impedance for use in comparatively low voltage and low frequency applications such as citizens' band (CB) communications systems. UHF connectors are also used in public address systems, closed circuit television (CCTV), civil defense, landing systems, ground control apparatus, ship-to-shore communications, and mobile radio equipment hookups between antenna and transmitters or receivers. 
   1.6 / 5.6       1.6 / 5.6 connectors are mechanically sturdy devices that feature a coupling mechanism. They are often used with equipment that requires resistance against environmental and mechanical stress. 1.6 / 5.6 connectors are also suitable for handling RF analog and digital signals in telecommunications systems. 
   7-16       7-16 connectors are designed for use in medium to high power communication systems. These connectors perform exceptionally well in multichannel cellular systems where power levels approximate 100 watts per channel. Designed for both flexible as well as corrugated cables, these connectors are used in a variety of cellular base station and broadcast communication applications.

   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Insertion Loss       Insertion loss (in dB) is the total RF power transmission loss through the modulator. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Amplitude Unbalance       Amplitude unbalance is the difference in power (measured in dB) between the I and Q output signals, or
  • AU (dB) = PI(dBm) - PQ(dBm)
 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Phase Unbalance       Phase unbalance is defined as the deviation from 90º of the phase angle difference of the I and Q output signals, or
  • PU(degrees) = 90º - (ØI - ØQ)
 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   VSWR       VSWR (Voltage Standing Wave Ratio) is a unitless ratio ranging from 1 to infinity, expressing the amount of reflected energy at the input of the device.  A value of one indicates that all the energy will pass through, while any other value indicates that a portion of the energy will be reflected. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
