Product Description
Applications
For 50 Ohm Source Impedance With its low input impedance, WMA3RA is
3T Frequency of 127.73 MHz
designed for 50 Ohm source impedance multi-
1.5 Ohm Input Impedance 0.45 dB Noise Figure 30.0 dBm Max PIN 20.0 dBm Output IP3 28.0 dB Gain 10.0 dBm P1dB 1.22:1 Output VSWR Unconditional Stable, k>1 Single Power Supply
channel coil applications. The pre-amp maintains excellent noise figure performance over source impedance variation that either comes from the different loads to the coils or not ideal design implementation of the coils.
