Description
Ground Connect.
Supply. Positive supply for LO, IF, biasing, and baseband sections. These pins should be
decoupled to the board ground using appropriate-sized capacitors. o a low impedance ground
plane.
Do not connect these pins.
Enable Control.
current. The default setting for this pin is open.
Local Oscillator Input. Pins must be ac-coupled. A differential drive through a balun
(recommended balun is the M/A-COM ETC1-1-13 for lower frequecies and Johanson xxxx for
higher frequecies) is necessary to achieve optimal performance.
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. Output 3 dB bandwidth is ~ 500 MHz.
A resistor to VPOS that optimizes third order intercept. For operation < 3GHz, R
operation from 3GHz to 4GHz, R
RF Input. A single-ended 50 Ω signal can be applied to the RF inputs through a 1:1 balun
(recommended balun is the M/A-COM ETC1-1-13 for lower frequecies and Johanson xxxx for
higher frequecies).
Exposed Paddle. Connect to a low impedance thermal and electrical ground plane.
