FUNCTION
MAX2660

MAX2663
MAX2671
1
Local-Oscillator Input. Apply a local-oscillator signal with an amplitude of -10dBm to
+5dBm for the MAX2671/MAX2673 or -5dBm to +2dBm for the MAX2660/ MAX2661/
MAX2663. AC-couple to the oscillator with a DC blocking capacitor. Nominal DC volt-
age is V
CC
- 0.4V to V
CC
- 1.0V.
MAX2673
2
Mixer Ground. Connect to the ground plane with a low-inductance connection.
3
Intermediate Frequency Input. AC-couple to the input signal with a DC blocking
capacitor. Nominal DC voltage is 1.37V.

6
Active-Low Shutdown Pin. Drive low to deactivate all part functions and reduce the
supply current to less than 1µA. For normal operation, drive high or connect to V
CC
.
5
Voltage Supply Rail, +2.7V to +5.5V. Bypass with a capacitor to the ground plane.
Capacitor value depends on desired operating frequency.
4
Radio Frequency Output. Open-collector output requires an inductor to V
CC
that is
part of an impedance-matching network. AC-couple to this pin using a blocking
capacitor that can be part of the impedance-matching network. See Applications
Information for details on impedance matching.
