XM1002-BD

Image Reject Mixer

34 - 46 GHz

Rev. V1

App Note [1] Biasing - As shown in the bonding diagram, the pHEMT mixer devices are operated using a

separate gate voltage Vg1. Set Vg1=-0.5V for optimum conversion loss performance.

App Note [2] Bias Arrangement - Each DC pad (Vg1) needs to have DC bypass capacitance (~100-200 pF) as

close to the device as possible. Additional DC bypass capacitance (~0.01 uF) is also recommended.

App Note [3] USB/LSB Selection -

LSB

IF2

USB

IF1

For Upper Side Band Operation (USB): With IF1

and IF2 connected to the direct port (0º) and cou-

pled port (90º) respectively as shown in the dia-

gram, the USB signal will reside on the isolated

port. The input port must be loaded with 50 ohms.

For Lower Side Band Operation (LSB): With IF1

and IF2 connected to the direct port (0º) and cou-

pled port (90º) respectively as shown in the dia-

gram, the LSB signal will reside on the input port.

The isolated port must be loaded with 50 ohms.

Note: The coupled port can be used as an alterna-

tive input but the port location of the Coupled and

Direct ports reverse.
