General Specifications
   Filter Technology       
   Your choices are...         
   Active Filter       The filter contains active components such as an amplifier or other powered components. 
   Passive Filter       The filter is designed with passive components and does not contain any active powered components to operate.  
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Filter Type       
   Your choices are...         
   Bandpass       Bandpass filters are active or passive circuits that pass signals from a specific frequency band and reject signals from out-of-band frequencies. Surface acoustic wave (SAW) filters, crystal filters, and cavity filters are types of bandpass filters. 
   Band Reject       Band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies. These devices are also known as bandstop or notch filters. 
   Low Pass       Low pass filters pass low frequencies and reject high frequencies. 
   High Pass       High pass filters pass high frequencies and reject low frequencies. 
   Other       Other unlisted filter types. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Filter Design       
   Your choices are...         
   Ceramic Filter       Filters are designed using piezoelectric ceramics to pass certain frequencies. 
   Crystal Filter       Filters are designed with a quartz crystal resonator. 
   SAW Filter       Filters are designed and manufactured using surface acoustic wave (SAW) technology. 
   Adjustable Filter       Filters are designed to be adjustable in frequency.  
   Other       Other unspecified filter designs.

Filter Performance
   Frequency (Fc)       The filter type determines the specified frequency (Fc). For bandpass and band reject filters, the specified frequency is the center frequency. For low pass filters, the specified frequency is the cut-off frequency. For high pass filters, the specified frequency is the cut-on frequency. 
   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.
   Bandwidth       Bandwidth is the range of frequencies that filters pass with minimal attenuation or, in the case of band reject filters, maximum attenuation. 
   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.
   Ripple       Ripple is the peak-to-peak variation of the passband response. Measured in decibels (dB), ripple is a function of the match of the device in the system. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Insertion Loss       Insertion loss is the total RF power transmission loss resulting from the insertion of a device in a transmission line. Insertion loss is defined as the ratio of signal power at the output of the inserted device to the signal power at the input of the inserted device.  
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   VSWR       Voltage standing wave ratio (VSWR) is a unit-less ratio ranging from 1 to infinity that expresses the amount of reflected energy. A value of 1 indicates that all of the energy passes. Any other value indicates that a portion of the energy is deflected. VSWR can also be expressed in decibels (dB) in terms of return loss. When there are impedance mismatches in a system, some of the transmitted energy is reflected back to the source. The frequency of the signal determines the amount of energy that is reflected. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.

Filter Package
   Package Type:       
   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.  
   Flatpack       Flat pack (FPAK) devices have gull wing or flat leads on two or four sides. They provide exceptional thermal and electrical performance and are available in cavity-up and cavity-down configurations. Flat pack devices are typically ceramic, hermetic, and surface-mounted. They are available in a variety of body sizes and pin counts. 
   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. 
   Other       Other unlisted packages.
