The SA605 is a high performance monolithic low-power 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 SA605 combines the functions of Signetics, SA602 and SA604A but features a higher mixer input

intercept point, higher IF bandwidth (25MHz) and temperature compensated RSSI and limiters permitting higher performance application. The SA605 is available in 20-lead dual-in-line plastic, 20-lead SOL (surface-mounted miniature package) and 20-lead SSOP (shrink small outline package). The SA605 and SA615 are functionally the same device types. The difference between the two devices lies in the guaranteed specifications. The SA615 has a higher ICC, lower input third order intercept point, lower conversion mixer gain, lower limiter gain, lower AM rejection, lower SINAD, higher THD, and higher RSSI error than the SA605. Both the SA605 and SA615 devices will meet the EIA specifications for AMPS and TACS cellular Radio applications. For additional technical information please refer to application notes AN1994, 1995 and 1996, which include example application diagrams, a complete overview of the product, and artwork for reference.
