RMDA20420
RF Components 20-42 GHz General Purpose MMIC Amplifier
ADVANCED INFORMATION
Description
The Raytheon RF Components RMDA20420 is a broadband general purpose driver amplifier
designed for use in point to point radio, point to multi-point communications, LMDS, SatCom and
other millimeter wave applications. The RMDA20420 is a fully matched GaAs MMIC utilizing
Raytheon RF Components’ advanced 0.15µm gate length PHEMT process.

Notes:
1. Operated at 25 °C, 50 Ohm system, Vd=+3.5 V, quiescent current (Idq)=350 mA.
2. Typical range of the negative gate voltage is -0.9 to –0.15 V to set typical Idq of 350 mA.
3. Production measurements for small signal gain are made over a frequency range of 20 to 40 GHz.
4. Saturated power measurements are not 100% tested, but guaranteed by design.
