PRODUCT INFORMATION

Description

The RMPA0951A-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 RF Components’ InGaP Heterojunction Bipolar Transistor (HBT)

process.

Notes:

1. No permanent damage with only one parameter set at extreme limit and other parameters typical.

2. Typical RF input powers for CDMA (-3 dBm) and AMPS mode (+2 dBm) operation.

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, Pout=28 dBm. Offset is ± 885 KHz, ± 1.98 MHz.

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

7. Guaranteed by design.

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