5692
The Netcom 5692 is a tunable high pass low pass filter covering 450 MHz to 750 MHz. It uses two tunable sections in series: a high pass with a cutoff (f1) from 450 to 670 MHz, and a low pass with a cutoff (f2) from 450 to 750 MHz. Each section has 32 states and is set on its own, so you choose both the centre frequency and the width of the passband.
This is the main difference from a fixed percentage bandpass filter, where the width follows the centre frequency and cannot be changed. With the 5692 you can open the passband wide for scanning, then close it down on a single channel, using the same part.
Control is by SPI interface. Passband insertion loss is 4.0 dB maximum for widths above 50 MHz. Rejection is 25 dB minimum at 20% below the high pass cutoff and 16 dB minimum at 20% above the low pass cutoff. RF power handling is +27 dBm and IIP3 is +40 dBm. Passband VSWR is 2:1. The part runs from 5.0 V at 50 mA, measures 0.650 x 0.375 x 0.150 inches and works from -40 to +85 °C.
