Description
Ground Connect.
I Channel and Q Channel Mixer Baseband Outputs. These outputs have a 50 Ω differential
output impedance (25 Ω per pin). Each output pair can swing 2 V p-p (differential) into a
load of 200 Ω. The output 3 dB bandwidth is ~400 MHz.
Supply. Positive supply for LO, IF, biasing, and baseband sections. Decouple these pins to
the board ground using the appropriate-sized capacitors.
Enable Control. When pulled low, the part is fully enabled; when pulled high, the part is
partially powered down and the output is disabled.
Local Oscillator Input. Pins must be ac-coupled. A differential drive through a balun is
necessary to achieve optimal performance. Recommended balun is the Mini-Circuits
TC1-1-13 for lower frequencies, the Johanson Technology 3600 balun for midband
frequencies, and the Johanson Technology 5400 balun for high band frequencies.
Balun choice depends on the desired frequency range of operation.

See the Circuit Description section for more details.
RF Input. A single-ended 50 Ω signal can be applied differentially to the RF inputs through
a 1:1 balun. Recommended balun is the Mini-Circuits TC1-1-13 for lower frequencies, the
Johanson Technology 3600 balun for midband frequencies, and the Johanson Technology
5400 balun for high band frequencies. Balun choice depends on the desired frequency
range of operation.
Exposed Paddle. Connect to a low impedance thermal and electrical ground plane.
NOTES
1. NC = NO CONNECT.
2. THE EXPOSED PAD SHOULD BE CONNECTED TO A
LOW IMPEDANCE THERMAL AND ELECTRICAL
GROUND PLANE.
