Noise reduction before the headset Varactor tuned aviation pre-selector features 30 dBm IP3 Safety first; music later TF0111 Tunable Avionics Pre-selector IP3 typical performance Even with GPS and autopilots, clear communication is still the most important element in aircraft operation. Increasing receiver sensitivity allows longer radio range but that comes at a price. Aviation radio happens to be close to FM (88 – 108 MHz). Strong signals from nearby 50,000 Watt FM stations can distort in the receiver input, interfering with the 5 – 25 Watt signals from the airport tower. Features New FAA rules took effect in January 2011 to manage FM station tower radiation patterns but that’s not enough. A filter is needed to block the FM – but the filter itself can’t overload and add it’s own distortion. The filter pass band also needs to be quite narrow since interfering sources can be close in frequency while the whole avionics band is fairly wide – this means the filter must be tunable or switched. Using a varactor tuned multi-pole approach gives a very small device – perfect for flight or portable radios. The MtronPTI TF0111 Avionics Pre-selector has an IP3 spec of 30 dBm minimum and can handle input power up to +20 dBm without damage. Analog tuned with a single control line, the TF111 comes in a 1.25” x 0.5” x 0.35” reflow hardened surface mount package.
