V2 DC Biasing Operation The IF port DC bias voltage (VD) and current requires a bias choke and DC blocking capacitor. The bias choke can be a ferrite bead (Murata BLM03HG601) . Both VG and the DC side of the ferrite bead should be bypassed with a capacitor (0.22 µF 0201). The VG pin can be biased through a resistor connected to a VD supply. A resistor value of 5812 x (VD-1.1) will provide the correct current into VG to bias the part. For best gain the IF port requires 2 to 3 volts of bias. The VG port can be set to 0.6 V which will bias the part to approximately 2 mA and allow a minimal LO power to be used (approx. -2 dBm). When the LO power is on the device current will increase to approximately 15 mA. Grounding It is recommended that the total ground (common mode) inductance not exceed 0.03 nH. This is equivalent to three 8 mil (200 µm) vias under the device on an 8 mil thick PC board combined with vias included in the ground plane around the package. RF / LO Combining The MAMX-011023 has only one pin for RF and LO so the LO and RF must be combined. For PCB applications a printed directional coupler may be used to combine the RF and LO. Also, two MAMX-011023 may be used in a balanced operation by combining the RF and LO in a “rat race” or similar coupling structure. The balanced operation will improve LO rejection at the IF. Typically the RF input to the main coupler line and the LO is injected through the coupled line to minimize loss and maintain low noise figure.

V2 Applications Section System usage of this Mixer The MAMX-011023 may be used in single ended, balanced, and image reject circuit configurations. Single Ended Mixer The single Ended mixer is the simplest use of the MAMX-011023. Some form of combiner is needed to put both the RF and LO signals on the input port and this combiner must allow low loss to the RF signal to preserve the low noise figure. A 10 dB quarter wavelength coupled line section can form a convenient and low cost combiner. The single ended mixer will have minimal rejection of RF, LO and image products at the IF. RF 4 Coupler 10 dB 10 GHz LO 2 W2 3 1 W1 MAMX-011023 50 Ω LO Balanced Mixer The balanced mixer will improve mixer performance by cancelling the LO at the IF output and cancelling RF second order products. Linearity will be improved by using two mixers and RF loss will be limited to the rat race and transformer insertion losses.
