RF2603
2.8V PCS UPCONVERTER
• TDMA/CDMA PCS Systems • Portable Battery-Powered Equipment
The RF2603 is a upconverter/pre-driver designed for
PCS systems. The device features single-ended IF and
LO inputs and single-ended RF output for ease of interface. The RF2603 is manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT)
process and is packaged in a TSSOP-16 package.

Pin Function Description Interface Schematic
1VCC
Supply Voltage pin. External bypassing is required. The trace length
between the pin and bypass capacitors should be minimized. The
ground side of the bypass capacitor should be connected immediately
to ground plane.
2NC
Not connected.
3NC
Not connected.
4GND
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
5LOIN
LO input pin. This pin is internally DC-biased and should be
DC-blocked if connected to a device with a DC level present. The input
impedance is 50Ω.
6GND
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
7RFOUT
RF output pin. This pin is internally DC-biased and should be
DC-blocked if connected to a device with a DC level present. This pin
must be externa lly matched for 50Ω output impedance.
8VCC
Supply Voltage pin. External bypassing is required. Either a length of
transmission line or external inductor is needed between this pin and
the bypass capacitor for tuning the output to 50Ω.
9NC
Not connected.
10 NC
Not connected.
11 GND
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
12 VCC
Supply Voltage pin. External bypassing is required. Either a length of
transmission line or external inductor is needed between this pin and
the bypass capacitor for tuning the mixer.
13 GND
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
14 IF IN
IF input pin. This pin is internally DC-biased and should be DC-blocked
if connected to a device with a DC level present.
15 NC
Not connected.
16 TX ENABLE
TX enable pin.
