Performance

Input Frequency Range | The range of input frequencies over which the converter is designed to operate. | ||
Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
Output Frequency Range | The range of output frequencies that the converter is designed to deliver. | ||
Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
Conversion Gain | Conversion gain is the net increase in power between the fundamental input signal and the desired output. It is calculated as the ratio (in dB) of the output power to the RF input power. It is a measure of the efficiency of the converter in providing frequency translation between the input RF signal and the output signal. | ||
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. | ||
Return Loss | Output return loss is the amount of power that is "lost" to the load and does not return as a reflection. Input return loss is the amount of power that is "lost" to the converter and does not return back to the source. Although "loss" has negative connotations, high return is usually desired. Return loss is commonly expressed in decibels (dB). For example, if one-half of the power does not reflect from the load/source, the return loss is 3 dB. Return loss can also be expressed in terms of voltage standing wave ratio (VSWR). | ||
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. | ||
Noise Figure | Noise figure (NF) is the ratio (in dB) of the signal-to-noise ratio at the input of the component and the signal-to-noise ratio measured at the output. It is a measure of the amount of noise added to the signal during normal operation. A low noise figure means better performance. The NF value sets the lower limit of the dynamic range of the amplifier. | ||
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. | ||
Power Output | The maximum output signal power of the converter (expressed in dBm). | ||
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. | ||
Number of Channels | The number of converters (channels) embedded in the device. | ||

Connectors | |||
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 50Ω and 75Ω 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 50Ω or 75Ω 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 50Ω impedance, but 75Ω 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. | ||

Features | |||
Your choices are... | |||
RoHS | Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. | ||
Alarms and Status Indicators | The converter has indicators to signal important operating statuses or warnings. | ||
Frequency Inversion | Frequency inversion is the process of inverting a signal frequency to produce a mirror image at a different frequency range. This is one of the most common scrambling methods. This process relocates the power level of each input frequency to a new position, calculated as the difference between the original frequency and the inversion frequency. | ||
Remote Control Interface | The converter has a port or interface that can be used to connect to a computer for remote operation and monitoring. | ||
Tunable | The converter can be tuned. | ||
