The layout is very critical in the performance of the receiver. We highly recommend our demo
board layout.
All of the inductors, the quad tank, and their shield must be grounded. A 10 F to 15 F or higher
value tantalum capacitor on the supply line is essential. A low frequency ESR screening test on this
capacitor will ensure consistent good sensitivity in production. A 0.1 F bypass capacitor on the
supply pin, and grounded near the 44.545 MHz oscillator improves sensitivity by 2 dB to 3 dB.
