| 35.0-45.0 GHz GaAs Receiver SMT, 7x7 mm January 2008 - Rev 24-Jan-08 R1008-QB Features Sub-harmonic, Image Reject Receiver Integrated LNA, Image Reject Mixer, LO Doubler/Buffer +2.0 dBm LO Drive Level 8.0 dB Conversion Gain 3.5 dB NF +5.0 dBm Input Third Order Intercept (IIP3) 7x7mm SMT package 100% RF and DC Testing General Description Mimix Broadband's 35.0-45.0 GHz packaged receiver has a noise figure of 3.5 dB and 5.0 dBm Input Third Order Intercept across the band. This device integrates a three stage LNA followed by an image reject resistive pHEMT mixer and includes an integrated LO doubler and buffer amplifier. The use of integrated LO doubler and LO buffer amplifier makes the provision of the LO easier than for fundamental mixers at these frequencies. I and Q mixer outputs are provided and an external 90 degree hybrid is required to select the desired sideband. The device comes in a 7x7mm SMT package that is RoHS compliant. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.

The device is operated by biasing VD=4.0V with ID=180 mA by adjusting the applied voltage on VG1. VG1 typically requires-0.5V to result in the drain current being 180mA. The nominal input impedance of this gate is 180Ohm, so it should be noted that the nominal gate current will be 2.7mA. Additionally, a fixed bias of VG2=-0.5V is required to bias the mixer and doubler. Adjusting VG2 above or below this value can adversely affect conversion gain, image rejection and intercept point performance. It is recommended to use active biasing to keep the currents constant as the RF power and temperature vary; this gives the most reproducible results. The diagram "Active Bias Circuit" demonstrates a possible method for active biasing. Depending on the supply voltage available and the power dissipation constraints, the bias circuit may be a single transistor or a low power operational amplifier, with a low value resistor in series with the drain supply used to sense the current. The gate of the pHEMT is controlled to maintain correct drain current and thus drain voltage. Typically the gate is protected with Silicon diodes to limit the applied voltage. Also, make sure to sequence the applied voltage to ensure negative gate bias is available before applying the positive drain supply Active Bias Circuit 5.0V 5k76 5R62 (sense) 4V, 180mA 3 Vd 100n 4.0V 1 MMBT3904 1 MMBT3906 10R 3 12k1 12k1 100R 2 2 -5.0V 1k0 Vg1 2 1 100n 3 3 BAV99 BAV99 Mimix Broadband, Inc., 10795 Rockley Rd., Houston, Texas 77099 Tel: 281.988.4600 Fax: 281.988.4615 mimixbroadband.com Characteristic Data and Specifications are subject to change without notice.
