General Description
The HMC926LP5E is a digitally controlled variable
gain amplifier which operates from 700 MHz to 2700
MHz, and can be programmed to provide between
+6.5 dB to +38 dB of gain, in 0.5 dB steps at 900
MHz. Gain control range is from +1 dB to +32.5 dB at
1900 MHz and from -4 dB to +27.5 dB at 2600 MHz.
The HMC926LP5E delivers noise figure of 4.4 dB in
its maximum gain state, with output IP3 of up to +45
dBm. The HMC926LP5E features a serial only gain
control interface, a user selectable power up state,
and a serial output for cascading other Hittite serially
controlled components.
