Trilithic’s RF and Microwave Components division has released a new programmable attenuator. Model 522095-1S-12V-TTL-R features a dynamic range of 95 dB in 1 dB steps over a frequency range of DC to 2.2 GHz.


Attenuation accuracy is +/-0.2 dB or 2 percent over the entire range. VSWR is 1.4:1 maximum and insertion loss is 4 dB maximum. Switching speed is 6 mS and the relay switch is rated at 5 million operations per cell. Operating voltage is 12 VDC at 15 mA per cell. The control protocol is TTL and via a 10-pin connector. The RF connectors are SMA female. This programmable attenuator is an ideal solution in many RF simulations, OEM test equipment and telecommunication lab applications. Delivery is stock to six weeks.
