iTR20420
20-42 GHz General Purpose MMIC
Amplifier
Description
The iTR20420 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 iTR20420 is a fully matched GaAs MMIC utilizing an 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.
