3.3V UNII Band Power Amplifier

MMIC/Switch Module for WLAN

PRODUCT INFORMATION

Description

The RTPA5250-130 is a small outline, highly integrated power amplifier and switch MMIC-based module for WLAN

applications in the 5.15 - 5.25, 5.25 - 5.35, and 5.725 - 5.825 GHz UNII (Unlicensed National Information

Infrastructure) bands. RF inputs and outputs are matched internally to 50 ohms to reduce circuit complexity. A

pair of PHEMT switches provide additional flexibility for designers of UNII band systems. The RTPA5250-130

utilizes Raytheon’s low cost, advanced 0.5 µm gate length power PHEMT process.

Features

Low Cost LTCC package (11.6 x 9.1 x 1.7mm)

38 dB small signal gain (typ.)

7 dB headroom for signals with high peak to average power ratio

Switches included for T/R and antenna diversity functions

RF Inputs and outputs matched to 50 Ohms

Process tolerant active bias eliminates process variations

Power-down mode reduces quiescent current to 9 mA when in receive mode

Antenna, RCV or XMT ports are internally matched when not in operation

Notes:

1. Output power and efficiency is the average value measured at ANT1 or ANT2 with diversity switch set to output for corresponding antenna.

Input shall be a 16QAM-modulated OFDM waveform with 52 sub-carriers spaced at 312.5 KHz. Module output power at ANT1 and ANT2

includes switch insertion loss.

2. Power out @ Idq=320 mA

3. Amplifier is unconditionally stable into all output VSWRs. Stated VSWR is required to achieve specified performance.

4. Amplifier output power and phase must settle to within 90% of final values within time specified.

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