RFMW announces design and sales support for Smiths Interconnect TSX Series chip attenuators with extended frequency range. The TSX series chip attenuators span DC to 50 GHz with 1 to 3 Watts of input power handling capability based on individual device attenuation values as follows: 0-1 dB attenuators are rated at 3 W, 2-3 dB rated at 2 W, 4-20 dB rated at 1 W. Q-band performance addresses new markets and applications including instrumentation, radar, satellite and 5G systems. In transmitters, low VSWR increases output power potential while the small, 0604 package size, ideal for pick and place manufacturing, reduces…

Radar receivers require low noise front ends to be able to detect targets at a long range. Simultaneously, they are frequently operated in an environment where a very high-power transmitter (a radar transmitter) will periodically leak into the receiver path, potentially damaging the receiver. A classic example of this is when a plane flies past a high-power radar transmitter, leading to damaging radiation levels for the plane’s receiver. This damage can be prevented by using a limiter. Figure 1: High power transmitters can damage high-sensitivity receivers An ideal RF limiter is a device that passes RF signals below a certain…
