20.0-38.0 GHz GaAs MMIC
Balanced Mixer
February 2007 - Rev 26-Feb-07
M1004-BD
App Note [1] Biasing - As shown in the bonding diagram, this device is operated by biasing Vg1 = -0.5V. Gate current
consumption is < 1mA.
App Note [2] Bias Arrangement - Each DC pad (Vg) 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 - IF1 and IF2 are fed through a 180º Hybrid coupler for optimum performance. IF1 can
be singly fed with IF2 terminated in 50 Ohm for ease of use. This will result in approximately 2 dB reduction in IP3 and
conversion gain performance.

USB
For Upper Side Band operation (USB):
With IF1 and IF2 connected to the
direct port (0º) and coupled port (180º)
respectively as shown in the diagram,
the USB signal will reside on the
isolated port. The input port must be
loaded with 50 ohms.

USB
For Lower Side Band operation (LSB):
With IF1 and IF2 connected to the
direct port (0º) and coupled port (180º)
respectively as shown in the diagram,
the LSB signal will reside on the input
port. The isolated port must be loaded
with 50 ohms.
