Text preview for : RGDA01(2-6 GHz GaAs pHEMT).pdf part of Rficsolutions.Inc RGDA01 The RGDA01 is 2.0 to 6.0 GHz GaAs Enhancement
mode psuedomorphic high electron mobility
transistor Driver Amplifier. The device is designed
for IEEE 802.11a/b/g, WLAN standards and Cellular
system.
The driver amplifier can provide upto 20 dBm power
output. The optimum performance of the chip can be
achieved by some off chip matching. The part is
biased with a single +3.3 V supply.
