Description: Low voltage mixer FM IF system

Features

* VCC = 2.7 V to 5.5 V
* Low power consumption: 8.6 mA (typical) at 3 V
* Wideband data output (1 MHz minimum)
* Fast RSSI rise and fall times
* Mixer input to >500 MHz

* XTAL oscillator effectiv

Applications

* and functions down to 2.7 V. The RF section is similar to the famous NE605. The data output provides a minimum bandwidth of 1 MHz to demodulate wideband data. The RSSI output is amplified and has access to the feedback pin. This enables the designer to level adjust the outputs or add filtering. The
