High performance low power mixer FM IF system
The NE615 is a high performance monolithic low-poer FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator (RSSI), and voltage regulator.
The NE615 combines the functions of Signetics' NE602 and NE604A, but features a higher mixer input intercept point, higher IF bandwidth (25MHz) and temperature compensated RSSI and limiters permitting higher performance application.
Features
* Low poer consumption: 5.7mA typical at 6V
* Mixer input to > 500MHz
* Mixer conversion power gain of 13dB at 45MHz
* Mixer noise figure of 4.6dB at 45MHz
* XTAL oscillator effective to 150MHz (L.C. oscillator to 1GHz local oscillator can be injected)
* 102dB of IF Amp/Limiter gain
* 25MHz limiter small signal bandwidth
* Temperature compensated logarithmic Received Signal Strength Indicator (RSSI) with a dynamic range in excess of 90dB
* Two audio outputs - muted and unmuted
* Low external component count; suitable for crystal/ceramic/LC filters
* Excellent sensitivity: 0.22uV int 50ohm matching network for 12dB SINAD (Signal to Noise and Distortion ratio) for 1kHz tone with RF at 45MHz and IF at 455kHz
* ESD hardened
Applications
* High performance communications receivers
* Single conversion VHF/UHF receivers
* SCA receivers
* RF level meter
* Spectrum analyser
* Instrumentation
* FSK and ASK data receivers
* Log amps
* Wideband low current amplification
