IF1+
IF output. Open collector output, requires external matching compo-
nents and DC connection to V
CC
.
This CMOS compatible pin controls the selection of the low or high
band signal path (See the State Control Truth Table). Local bypass
capacitor required.
LO band local oscillator input. This pin is AC-coupled and matched to
50
.
See pin 16.

TX/RX
This CMOS compatible TX/RX mode select Power Control Pin. CMOS
compatible signal controlling the functional state of the device (See the
State Control Truth Table). Local bypass capacitor required.
Low band RF mixer input. Although the base of the mixer input transis-
tor is AC coupled, this pin serves a dual purpose of providing a DC bias
path via external inductor to GND. The typical input impedance is 8
real and requires external matching to 50
.

Bias supply voltage. Local bypass capacitor required.
Low band LNA output. Bias for the LNA is provided through this pin,
hence it should be connected to VCC through and inductor.
See pin 3.
