1. C-message: The C-message and de-emphasis filter combination has a peak gain of 10 for accurate measurements. Without the gain, the
2. Ceramic filters: The ceramic filters can be 30kHz SFG455A3s made by Murata which have 30kHz IF bandwidth (they come in blue), or
3. RF generator: Set your RF generator at 45.000MHz, use a 1kHz modulation frequency and a 6kHz deviation if you use 16kHz filters, or
4. Sensitivity: The measured typical sensitivity for 12dB SINAD should be 0.35 V or –116dBm at the RF input.
5. Layout: The layout is very critical in the performance of the receiver. We highly recommend our demo board layout.
6. 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
7. Supply bypass and shielding: All of the inductors, the quad tank, and their shield must be grounded. A 10-15 F or higher value tantalum
8. R5 can be used to bias the oscillator transistor at a higher current for operation above 45MHz. Recommended value is 22k , but should not
