Notes
Note 1: The HMC611LP4 & HMC611LP4E evaluation boards are pre-assembled for single-ended input, and detector/RSSI mode.
Note 2: For detector mode, connect high impedance volt meter to the LOGOUT port, and make no connection to VSET. LOGOUT
is shorted to VSET by R9, as required for detector mode.
Note 3: For controller mode, remove R9 and install 0 ohm resistor (R11), then make appropriate connection to LOGOUT and VSET.
In controller mode, the LOGOUT output can be used to drive a variable gain amplifier, or a variable attenuator, either
directly or through a buffer or microcontroller. VSET should be connected to an external supply, typically between +0.6
and +1.9V.
