Function

Positive Supply Voltage for the LO Buffer: 4.75 V to 5.25 V.

AC Ground for Limiting LO Amplifier. Internally biased to Vs − 1.6 V. AC-couple to ground.

LO Input. Nominal input level 0 dBm. Input level range −10 dBm to +4 dBm (relative to 50 Ω). Internally biased to Vs − 1.6 V. AC-couple.

Device Common (DC Ground).

Differential IF Outputs (Open Collectors). Each requires dc bias of 5.00 V (nominal).

Mixer Bias Voltage. Connect resistor from EXRB to ground. Typical value of 1.82 kΩ sets mixer current to nominal value. Minimum resistor value from EXRB to ground = 1.8 kΩ. Internally biased to 1.17 V.

Connect to Ground for Normal Operation. Connect pin to VS for disable mode. Positive Supply Voltage for the DC Bias Cell: 4.75 V to 5.25 V.

AC Ground for RF Input. Internally biased to 2.4 V. AC-couple to ground. RF Input. Internally biased to 2.4 V. Must be ac-coupled.

Positive Supply Voltage for the Mixer: 4.75 V to 5.25 V.
