3V Cellular CDMA Power Amplifier Module

Description

ADVANCED INFORMATION

The RMPA0951-102 is a dual mode, small-outline power amplifier module (PAM) for Cellular CDMA personal

communication system applications. The PA is internally-matched to 50 ohms and DC blocked which minimizes the

use of external components and reduces circuit complexity for system designers. High AMPS/CDMA efficiency and

good linearity are achieved using Raytheon’s Heterojunction Bipolar Transistor (HBT) process.

Features

Single positive-supply operation.

High dual-mode (AMPS/CDMA) efficiency and good linearity

Small size: 6.0 x 6.0 x 1.5 mm3 LCC package.

50-ohm matched input and output module.

Adjustable quiescent current and power-down mode.

Notes:

1. No permanent damage with only one parameter set at extreme limit. Other parameters at typical values.

2. Typical RF input power for +28 dBm CDMA (-3 dBm) and +31.5 dBm AMPS-Mode output powers.

3. All parameters to be met at Ta = +25°C, Vcc = +3.5V, Vref=3.0V and load VSWR ≤ 1.2:1.

4. Load VSWR ≤ 6:1 all phase angles.

5. CDMA Waveform measured using the ratio of the average power within the 1.23 MHz signal channel to the power within a

30 kHz resolution bandwidth at a 885 KHz offset.

6. No applied RF signal. Vcc=+3.5V nominal, Vref=+0.2V maximum.

Characteristic performance data and specifications are subject to change without notice.
