5779-9.5
The Netcom 5779-9.5 is a tunable bandpass filter covering 1.3 GHz to 1.7 GHz in the L-band. The centre frequency is set in 1 MHz steps and the 3 dB bandwidth is 9.5% of the tuned frequency. The filter settles on a new frequency in 10 microseconds.
It is part of the TunePro 2W series and handles 2 watts (+33 dBm P1dB) in a 0.575 x 0.575 inch surface mount package. IIP3 is +45 dBm and insertion loss is 4.5 dB typical, the lowest of the three TunePro parts in this size. Noise figure is less than 0.5 dB above the insertion loss. Rejection is 10 dB at 10% away from the tuned frequency, 15 dB at 15% away and 18 dB at 20% away. Control is by SPI serial interface. The part runs from 3.3 VDC at 30 mA and works from -40 to +85 °C.
The 9.5% passband makes this a preselector, not a channel filter. It passes a wide or hopping signal whole while keeping strong out of band energy away from the receiver front end.
