PCS CDMA LNA / Downconverter, 1.8—2.0 GHz
Pin Configuration
PIN No. PIN
Description
1
LO VDD LO Amplifier Supply Voltage. RF bypassing required.
2
LO In Local Oscillator Input (-10 to -7 dBm) (DC blocked)
3
GND DC and RF ground
4
IF Out IF Output and Downconverter - must be externally
matched to input impedance of IF Filter.
5
IF Match Matching between I FA and Mixer - requires an inductor
to ground.
6
GND DC and RF ground
7 LNA VDD1 LNA Stage 1 supply voltage. RF bypassing required.
8
LNA In RF Input to LNA. External matching required.
9 LNA SRC Source of LNA output stage FET. RF bypassing
required. Off-chip resistor may be used to increase IP3.
10 LNA Out 50Ω==Output of LNA. (DC Blocked)
11 LNA VDD2 LNA Stage 2 supply voltage. RF bypassing required.
12
GND DC and RF ground.
13
IF BYP IF Bypass of Mixer. Required DC block and RF/IF
ground.
14
GND DC and RF ground
15 RFA VDD RFA supply voltage. RF bypassing required.
16
RFA In 50Ω==Input of RFA. (DC blocking required)

1. Saw filter characteristics to be determined by customer, depending on band of operation. Sample boards are supplied with 3 dB pi pad installed in
place of saw filter, to emulate typical worst case loss. Data supplied with sample board is measured over US PCS1900 Rx Band.
