4. Supply bypass and shielding: All of the inductors, the quad tank, and their shield must be grounded. A 0.1 F bypass capacitor on the supply
1. 10 dB S/N corresponds to BER = 10
1. RF generator: Set your RF generator at 110.592 MHz, use a 100 kHz modulation frequency and a 288 kHz deviation.
2. Layout: The layout is very critical in the performance of the receiver. We highly recommend our demo board layout.
3. RSSI: The smallest RSSI voltage (i.e., when no RF input is present and the input is terminated) is a measure of the quality of the layout and

design. If the lowest RSSI voltage is 500 mV or higher, it means the receiver is in regenerative mode. In that case, the receiver sensitivity
will be worse than expected.
