Mod_TX_PE
Digital input control to enable the Modulator section. Enable logic level is High for transmit.
42
Mod_TX_IF_Out
Modulator open collector output, single ended. Termination resistor to V
CC
with a typical value of 250
.
44
Mod_LO_In
(2XLO)
Single ended local oscillator current input. Frequency of input signal must be twice the required modulator carrier
LO frequency. Input current is optimum at 200
μ
A
RMS
. Input matching networks and filters can be designed for a
wide range of power and impedances at this port. Typical input impedance is 130
.
This pin requires AC coupling.
NOTE: High second harmonic content input waveforms may degrade I/Q phase accuracy.
45
Mod_V
CC
Modulator supply pin. Use high quality decoupling capacitors right at the pin.
46
Mod_LO_Out
Divide by 2 buffered output reference from “Mod_LO_in” input. Used for external applications where the
modulating and demodulating carrier reference frequency is required. 50
single end driving capability. AC
coupling is required. This output can be disabled by shorting to V
CC
or floating pin 50.
47
Mod_V
CC
Modulator supply pin. Use high quality decoupling capacitors right at the pin.
48
MOD_BYP
This pin must be connected to pin 49 and decoupled to gnd. (Note 1)
49
MOD_BYP
This pin must be connected to pin 48. (Note 1)
50
LO_GND
When grounded, this pin enables the LO buffer (Mod_LO_Out). When open (NC) it disables the LO buffer.
55
IF_AGC_IN
AC coupled input to the AGC amplifier.
57
AGC_V
CC
AGC supply pin supply pin. Use high quality decoupling capacitors right at the pin.
59
AGC_CTRL
AGC control DC control voltage input requires external resistor to set scale factor. 10K for optimum temp. co. May
require decoupling filtering capacitor.
61
AGC_V
CC
AGC supply pin supply pin. Use high quality decoupling capacitors right at the pin.
63
AGC_PE
Digital input control for the AGC amplifier. Enable logic level is High.
65
AGC_IF_OUT
AGC amplifier output. Output impedance of 250
. Need to be connected to V
CC
by an inductor with reactance
well above 250
.
67
AGC_V
CC
AGC supply pin supply pin. Use high quality decoupling capacitors right at the pin.

Pinout
GND
All remaining pins not listed above must be connected to a solid ground plane.
NOTE:
1. If pin 50 is grounded, otherwise float.
