RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

18.0 to 40.0 GHz Successive Detection Log Video Amplifier (SDLVA)
PMI Model No. SDLVA-18G40G-65-CD-292FF is a Successive Detection Log Video Amplifier (SDLVA) that operates between the 18.0 to 40.0 GHz frequency range. It has a dynamic range of 65 dB, log slope of 25 mV/dB and a nominal video bandwidth of 32 MHz. Furthermore, it has been designed using cutting edge GaAs technology which provides stunning performance and reliability in a compact package making it an optimum solution for high speed channelized receiver applications.
6380 to 7440 GHz Voltage Variable Attenuator
PMI Model No. DTA-6380M7440M-60-9BDIFF-SFF is a Voltage Variable Attenuator with a control interface which allows for nine differential inputs to control the attenuator settings with a LSB of 0.25 dB and a minimum attenuation of 50 dB. This attenuator operates over the frequency range of 6380 to 7440 GHz.
1.0 GHz to 1.1 GHz Single Pole, Two Throw Hermetically Sealed Reflective Switch
PMI Model No. P2T-1G1R1G-25-R-SFF-100W is a Single Pole, Two Throw Hermetically Sealed Reflective Switch designed to operate over the 1.0 GHz to 1.1 GHz frequency range. This model is designed to handle 100 watts average input power and 5 KW peak having a 17 μsec pulse width and 2% duty cycle.
0 to 180 Degree Bi-Phase Modulator/Phase Shifter
PMI Model No. PS-90-2040 Opt HS15NS is a Miniature, 0 to 180 Degree Bi-Phase Modulator/Phase Shifter with TTL control logic (ECL logic available) operating over a frequency range of 2.0 to 4.0 GHz with a maximum insertion loss of 2.5 dB and VSWR better than 2.0:1. This model provides two phase states, namely 0 degrees and 180 degrees and is controlled via single line TTL. The phase state is switched in 15 ns or less and can handle input power levels up to 0.5 watt CW, 1 us pulse width. DC voltage requirement is +5 and -5. This unit is supplied in a package measuring 1.00" x 1.00" x 0.50".
