Description
No internal connection. May be grounded or connected on adjacent
signal or left floating. Connect to ground for best results.
No internal connection. May be grounded or connected on adjacent
signal or left floating. Connect to ground for best results.
Received signal strength indicator. Connect 8.2pF to ground. Output
impedance is 40k
in parallel with 2pF.
DC feedback capacitor for in-phase channel. Requires decoupling
capacitor to ground. (22nF recommended)
DC feedback capacitor for quadrature channel. Requires capacitor to
ground. (22nF recommended)
Supply for the I and Q data amps.This pin should be bypassed with a
10nF capacitor connected as direct as possible to GND3. Ground this
pin if data amps are not used.
Gain control reference voltage. No current should be drawn from this
pin (<50
μ
A). 2.0V nominal.
No internal connection. May be grounded or connected on adjacent
signal or left floating. Connect to ground for best results.
This pin requires a resistor to ground to set the baseband LPF band-
width of the receiver and transmit GmC filter amps.
Supply for the I and Q baseband and GmC filters. This pin should be
bypassed with a 10nF capacitor.
This is a bypass pin for the bias circuits of the GmC filter amps and for
I/Q inputs. No current should be drawn from this pin (<10
μ
A). 1.7V
nominal.
Receiver IF and baseband amp gain control voltage. Negative slope.

No internal connection. May be grounded or connected on adjacent
signal or left floating. Connect to ground for best results.
Ground for all circuitry in the device. A very low inductance from the
base to the PCB groundplane is essential for good performance. Use
an array of vias immediately underneath the device.
This diode structure is used to provide electrostatic discharge protec-
tion to 3kV using the Human body model. The following pins are pro-
tected: 3-6, 9, 10, 12, 26-34, 38-42, 44-47.
