Supply Voltage (VCC2)
This pin is VCC supply for the Limiter,
Quadrature Detector, data slicer and RSSI
64 k
buffer circuits. In the application PC board this
pin is tied to a common VCC trace with VCC1.

Limiter Input
The limiter input impedance is 330 Ω.

Limiter Decoupling
Decoupling capacitors are placed directly at
these pins and to VCC (RF ground). Use the
same procedure as in the IF decoupling.
No Connects
There is no internal connection to these pins;
however it is recommended that these pins be
connected externally to VCC (RF ground).
Limiter Output
The output impedance is low. The limiter
drives a quadrature detector circuit with in–
phase and quadrature phase signals.
Quadrature Detector Circuit
The quadrature detector is a doubly balanced
four–quadrant multiplier with an internal 5.0 pF
capacitor between Pins 12 and 13. An external
capacitor may be added to increase the IF
signal to Pin 13. The quadrature detector pin is
provided to connect the external RLC parallel
resonant network which provides the 90 degree
phase shift and drives the quadrature detector.
Detector Buffer Amplifier
This is an inverting amplifier. An external feed-
back resistor from Pin 17 to 15, (the inverting
input) controls the output amplitude; another
resistor from Pin 15 to the negative supply
(Pin 16) sets the DC output level. A 1:1 resistor
ratio sets the output DC level at two VBE with
respect to VEE. A small capacitor from Pin 17 to
15 can be used to set the bandwidth.
Supply Ground (VEE2)
In the PCB layout, the ground pins (also applies
to Pin 26) should be connected directly to
chassis ground. Decoupling capacitors to VCC
should be placed directly at the ground pins.
