Configured as a full-duplex configuration, the WSA-00178 features advanced Psuedo-Elliptic filter response for low loss/noise figure and superior rejection contributing to the units extremely low typical noise figures of < 1.7 dB typical while simultaneously offering sharp rejection below and above the receive passband. The WSA-00178 utilizes e-PHEMT LNA technology, providing low-noise figure and high third-order input intercept (IIP3) of +15 dBm minimum. The WSA-00178 offers automatic bypass operation when either LNA transistors fail, or when the supply voltage falls outside of normal operating range. The transmit through path provides a minimum of 40 dBc rejection in the receive passband, while transmit passband insertion loss is specified as 0.5 dB maximum. Transmit passband power handling is specified as 100 watts CW and 1500 watts peak instantaneous, while IMD is specified at 114 dBm maximum in the receive band with two +43 dBm carriers applied within the transmit passband. DC input power is specified as +10 to +15 VDC at 200 mA maximum. Dimensions are 11.6 × 8.7 × 3.5", including mounting feet and 7/16-DIN connectors. Weight is 10 lbs nominal. Wind loading is specified at < 10 lbs @ 100 mph. The operating temperature range is 40° to +60°(C.
