HMC602LP4 / 602LP4E v03.0209 70 dB, LOGARITHMICDETECTOR / CONTROLLER, 1 - 8000 MHzPin Descriptions (Continued) Pin Number Function Description Interface Schematic 21, 22 N/C The user should not connect to these pins. Package Base GND Exposed paddle must be connected to RF and DC ground. Application & Evaluation PCB Schematic 12 T S - SM R O T C E T E R D E W O P Notes Note 1: The HMC602LP4 & HMC602LP4E 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 amplifi er, 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.
