pin FuncTions
RFA, RFB (Pins 1, 6): Single-Ended RF Inputs for Chan-
nels A and B. These pins are internally connected to the
primary sides of the RF input transformers, which have
low
DC resistance to ground. Series DC-blocking capaci
-
tors should be used to avoid damage to the integrated
transformer when DC voltage is present at the RF inputs.
The RF inputs are impedance matched when the LO input
is driven with a 0±6dBm source between 1.5GHz and
2.5GHz and the channels are enabled.
CTA, CTB (Pins 2, 5): RF Transformer Secondary Center-
Tap on Channels A and B. These pins may require bypass
capacitors to ground to optimize IIP3 performance. Each
pin has an internally generated bias voltage of 1.2V and
must be DC-isolated from ground and V
CC
.
GND (Pins 3, 4, 7, 13, 15, 24, Exposed Pad Pin 25):
Ground. These pins must be soldered to the RF ground
plane on the circuit board. The exposed pad metal of the
package provides both electrical contact to ground and
good thermal contact to the printed circuit board.
