Product Summary

The SA639DH is a low-voltage high performance monolithic FM IF system with high-speed RSSI incorporating a mixer/oscillator, two wideband limiting intermediate frequency amplifiers, quadrature detector, logarithmic received signal strength indicator (RSSI), fast RSSI op amps, voltage regulator, wideband data output, post detection filter amplifier and data switch. The SA639DH is available in 24-lead TSSOP (Thin shrink small outline package). The SA639DH was designed for high bandwidth portable communication applications and will function down to 2.7V. The RF section is similar to the famous NE605. The data output provides a minimum bandwidth of 1MHz 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.

Parametrics

SA639DH absolute maximum ratings: (1)VCC Single supply voltage: -0.3 to 6 V; (2)VIN Voltage applied to any other pin1: -0.3 to (VCC+0.3) V; (3)TSTG Storage temperature range: -65 to +150 ℃; (4)TA Operating ambient temperature range SA6392: -40 to +85 ℃.

Features

SA639DH features: (1)VCC = 2.7 to 5.5V; (2)Low power consumption: 8.6mA typ at 3V; (3)Wideband data output (1MHz min.); (4)Fast RSSI rise and fall times; (5)Mixer input to >500MHz; (6)Mixer conversion power gain of 9.2dB and noise figure of 11dB at 110MHz.
