High performance low power mixer FM IF system

DESCRIPTION

The SA615 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

SA615 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 SA615 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 I

intercept point, lower conversion mixer gain, lower limiter gain, lower

AM rejection, lower SINAD, higher THD, and higher RSSI error than

the SA615. Both the SA605 and SA615 devices will meet the EIA

specifications for AMPS and TACS cellular radio applications.

AN1994, 1995 and 1996, which include example application

diagrams, a complete overview of the product, and artwork for
