Description

1, 4 to 6,

17 to 19

VPA, VPL, VPB, VPX

Supply. Positive supply for LO, IF, biasing and baseband sections, respectively. These pins should

be decoupled to board ground using appropriate sized capacitors.

2, 7, 10 to 12,

20, 23, 24

COM, CML, CMRF

Ground. Connect to a low impedance ground plane.

3

BIAS

Bias Control. A resistor can be connected between BIAS and COM to reduce the mixer core current.

The default setting for this pin is open.

8, 9

LOIP, LOIN

Local Oscillator. External LO input is at 2xLO frequency. A single-ended LO at 0 dBm can be applied

through a 1000 pF capacitor to LOIP. LOIN should be ac-grounded, also using a 1000 pF. These inputs

can also be driven differentially through a balun (recommended balun is M/A-COM ETC1-1-13).

13 to 16

ILO, IHI, QLO, QHI

I-Channel and Q-Channel Mixer Baseband Outputs. These outputs have a 50 Ω differential output

impedance (25 Ω per pin). The bias level on these pins is equal to VPOS − 2.8 V. Each output pair can

swing 2 V p-p (differential) into a load of 200 Ω. Output 3 dB bandwidth is 240 MHz.

21, 22

RFIN, RFIP

RF Input. A single-ended 50 Ω signal can be applied to the RF inputs through a 1:1 balun (recommended

balun is M/A-COM ETC1-1-13). Ground-referenced inductors must also be connected to RFIP and

RFIN (recommended values = 120 nH).

EP

Exposed Paddle. Connect to a low impedance ground plane
