The low profile 16 pin 3 x 3 x 0.9 mm package with internal matching on both input and output to 50 Ohms minimizes next level PCB space and allows for simplified integration. The onchip detector provides power sensing capability while the bias control provides power saving shutdown capability. The PA’s industry leading low power consumption and excellent linearity are achieved using our InGaP Heterojunction Bipolar Transistor (HBT) technology. ■ Internally matched to 50 Ohms and DC blocked RF input/ output ■ Optimized for use in 802.11b/g applications Device Electrical Characteristics1 802.11g OFDM Modulation (176 µs burst time, 100 µs idle time) 54 Mbps Data Rate, 16.7 MHz Bandwidth Parameter Frequency Collector Supply Voltage Mirror Supply Voltage Mirror Supply Current Gain Tota...
