Z-Communications Inc. announces the introduction of a high linearity power amplifier (5 W average) for emerging 802.16 WiMAX base station applications. The first in the series of power amplifier products for WiMAX, ZPA3436-5W operates over the 3.4 to 3.6 GHz band with a typical gain of 46 dB and 37 dBm OFDM output power for 64 QAM, 3/4 coding, 3.5 MHz channel bandwidth, 256 carriers.
The superior design incorporating the latest in high power device technology achieves Error Vector Magnitude (EVM) performance of 2 percent at 37 dBm linear output power. The power amplifier is biased at 28 V and draws about 3.5A DC current. The design is lead free and the SMA connectorized package measures only 9” x 4” x 1.5” typical without external heat sink.
