Table 4. Pin Function Descriptions
Pin No. Mnemonic Function
1 VPLO Positive Supply Voltage for the LO Buffer: 4.75 V to 5.25 V.
2 LOCM AC Ground for Limiting LO Amplifier, AC-Coupled to Ground.
3 LOIN LO Input. Nominal input level 0 dBm, input level range −10 dBm to +4 dBm, re: 50 Ω, ac-coupled.
4, 5, 8, 9, 13 COMM Device Common (DC Ground).
6, 7 IFOM, IFOP Differential IF Outputs; Open Collectors, Each Requires DC Bias of 5.00 V (Nominal).
10 EXRB
Mixer Bias Voltage, Connect Resistor from EXRB to Ground, Typical Value of 2.43 kΩ
Sets Mixer Current to Nominal Value. Minimum resistor value from EXRB to ground = 2.4 kΩ.
11 PWDN Connect to Ground for Normal Operation. Connect pin to V
S
for disable mode.
12 VPDC Positive Supply Voltage for the DC Bias Cell: 4.75 V to 5.25 V.
14 RFCM AC Ground for RF Input, AC-Coupled to Ground.
15 RFIN RF Input. Must be ac-coupled.
16 VPMX Positive Supply Voltage for the Mixer: 4.75 V to 5.25 V.
