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 m gate length power PHEMT process. 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
