WA Series Balanced Amplifiers
WA Series Low Noise Amplifiers
WA series low noise amplifiers are the balance type LNA with alarm capability in some of the products. Besides offering very low noise figure and wide bandwidth, the LNA have high linearity with unconditional stable design. The noise figures are from 0.40 dB to 1.0 dB and IP3 from 30 dBm to 40 dBm.The amplifiers cover the frequency bands of VHF, UHF, Cellular, GSM, DCS, PCS, 3G, C, and wireless LAN. The built-in alarm capabilities include Branch 1 and Branch 2 alarms, Soft Failure alarm, Hard Failure alarm, Soft alarm Open-Collector, and Hard alarm Open-Collector.
The LNA may be available in the PCB form (without housing) and thus more cost effective and easier to fit in your housing. Contact us for availability

[1] Measured at room temperature. Add 0.2 dB typical at 85 Co.
[2] Temperature difference between highest channel temperatures to case.
[3] Alarm 1--the amplifier has each branch alarm, soft alarm, hard alarm, soft alarm open collector, hard alarm open collector.
All alarm outputs are TTL type with 5.0 V under normal operation and 0 V under failure mode.
