RMPA5255 4.9–5.9 GHz WLAN Linear Power Amplifier Module February 2005 RMPA5255 4.9–5.9 GHz WLAN Linear Power Amplifier Module Features Description ■Full 4.9 to 5.9 GHz operation The RMPA5255 power amplifier module is designed for high performance WLAN applications in the 4.9–5.9 GHz frequency■34 dB small signal gain band. The 10 pin, 5 x 5 x 1.5 mm package with internal match- ■230 mA total current at 18 dBm modulated power out ing on both input and output to 50Ω, and internal bias network ■2.3% EVM at 18 dBm modulated power out components, allow for extremely simplified integration. An on- ■3.3 V collector supply voltage chip detector provides power sensing capability. The PA’s low ■Integrated power detector with 20 dB dynamic range power consumption and excellent linearity are achieved using our InGaP Heterojunction Bipolar Transistor (HBT) technology.■Lead-free 5 x 5 x 1.5 mm leadless package ■Internally matched to 50Ω and DC blocked RF input/output ■Internal DC bias de-coupling ■Optimized for use in 802.11a applications Device 1 Electrical Characteristics 802.11a OFDM Modulation (176 µs burst time, 100 µs idle time) 54 Mbps Data Rate, 16.7 MHz Bandwidth Parameter Min Typ Max Units Frequency 4.9 5.9 GHz Collector Supply Voltage 3.0 3.3 3.6 V Mirror Supply Voltage 2.9 V Mirror Supply Current 26 mA Gain 33 dB Total Current @ 18dBm Pout 230 mA 2 EVM @ 18dBm Pout 2.3 % Detector Output @ 18dBm Pout 450 mV 3 Detector Threshold 5dBm Notes: 1. VCC = 3.3V, VPC = 2.9V, T = 25°C, PA is constantly biased, 50Ω system. A 2. Percentage includes system noise floor of EVM = 0.8%. 3. P measured at P corresponding to power detection threshold.
