Description

Millitech series MXP balanced mixers are high performance broadband mixers in a very compact size. They offer low conversion loss and low noise figure over a wide range of IF and local oscillator frequencies. Series MXP covers frequencies from 26.5 to 140 GHz in seven waveguide bands. LO agility (swept LO) and extremely broadband IF are attainable.

MXP single-balanced mixers use GaAs Schottky Barrier Diodes and can operate with relatively low local oscillator power, generally 13 to 15 dBm. Custom models can be made to your specification. Special designs with LO input waveguide in a higher or lower waveguide band can be provided. External waveguide filters, LO reject filters, and compact 90º waveguide twists allow the user to change the mixer waveguide orientation (LO, RF or both) without taking much additional space. Detachable low-noise IF amplifiers are offered as options with these mixers.

When only a limited local oscillator power (0 to +3 dBm) is available, DC biasable series MB1 mixers are recommended. Millitech also offers a harmonic mixer to operate with fractional LO frequencies (series MSH).

Noise figure (DSB) is typically the conversion loss minus 3 dB, plus the IF amplifier
noise figure. Some typical amplifier choices:

IF Amplifier Frequency IF Amplifier Noise Figure (typ/max) Gain (typ)
0.1-4 GHz 1.5 dB / 1.7 dB 35 dB
1-8 GHz 1.5 dB / 2.0 dB 33 dB
2-18 GHz 3.0 dB / 5.0 dB 33 dB
6-18 GHz 2.0 dB / 2.75 dB 30 dB
26.5-40 GHz 3.5 dB / 4.5 dB 22 dB

Other IF ranges are also available, some with lower noise figure. Consult Millitech.

Examples:

To Order: a fullband fundamental mixer in WR-10 with LO and RF sweep

Specify: MXP-10-FXFL1, with the IF specified by the customer for what IF that the mixer will be tested. Generally, the test data will be ~ 10 test points across the RF band at the IF chosen. Additional test data or a specific test plan can be quoted.

To Order: a fullband fundamental mixer in WR-10 with LO fixed and RF swept

Specify: MXP-10-FSXL1, with the fixed LO specified by the customer. Test data will again generally be ~ 10 test points across the RF band with the LO fixed, constrained by the maximum IF shown in the spec. table (35 GHz for MXP-10).
