Power Amplifier Spectral Response

Under Modulation Drive (

≠/4 DQPSK,

a = 0.5, 384 kB/sec, 9-bit PN code)

Transmit/Receive Switch Performance

1. Spectral output is tested under the following conditions:

Modulation scheme is

≠/4 DQPSK with a bit transfer rate of 384

kB/sec and a root Nyquist filter with a = 0.5 per RCR STD-28.

The spectrum analyzer settings are as follows:

Resolution bandwidth: 10 kHz

Video bandwidth: 100 kHz

Sweep time: 5 seconds

2. This chart documents the modulated output power delivered

for a fixed adjacent channel interference (ACI) rejection of 55
