Product specification
SA615
High performance low power mixer FM IF system
2
1997 Nov 07
853-1402 18665
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 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 SA615. 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.
