HMC601LP4 / 601LP4E

v01.0509

75 dB, FAST SETTLING, LOGARITHMIC

DETECTOR / CONTROLLER 10 - 4000 MHz

Application & Evaluation PCB Schematic

Notes

Note 1: The HMC601LP4 & HMC601LP4E evaluation boards are pre-assembled for single-ended input, and detector/RSSI mode.

Note 2: For single-ended input operation, use the INP port and make no connection to INN. INN is AC coupled to ground by C2

Note 3: For differential input, remove C2, and install a 1000pF capacitor in series with INN at location shown.

Note 4: For detector mode, connect high impedence volt meter to the LOGOUT port, and make no connection to VSET. LOGOUT

is shorted to VSET by R3, as required for detector mode.

Note 5: For controller mode, remove R3 and 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.
