Functional Diagram
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.
