6 / 6 page MRFIC2001 6 MOTOROLA RF DEVICE DATA Matching the LO port to 50 ohms can be done several ways. The recommended approach is a series inductor as close to the IC as possible. The inductor value is small enough (~8 –15 nH depending on LO frequency) to be printed on the board. A DC block is required and should not be placed between the inductor and IC since this will prevent the inductor from being close enough to the IC to provide a good match. The IF port is an open collector resulting in a very high out- put impedance. For optimum linearity (IP3), the IF port should be loaded with a 1000 ohm load-line. Since the output requires a bias inductor and blocking capacitor, the IF filter impedance can be transformed to 1000 ohms with these two elements. If a low output VSWR is desired (to reduce IF filter ripple), a 2.0 – 4.0 K ohm resistor can be placed in parallel with the bias inductor. This will reduce the conversion gain by 1.0 – 2.0 dB. The RF port is nearly 55 ohms resistive in series with a small amount of capacitive reactance, which results in a 12–13 dB return loss. If a higher return loss is desired, a 3.0 – 4.0 nH series inductor printed on the board as close to the IC as possible will improve it to over 20 dB. A DC block is also required. Supply decoupling must be done as close to the IC as pos- sible. A 1000 pF capacitor is recommended. An additional 100 pF capacitor and an RF choke are recommended to keep the LO signal off the supply line. Enabling/Disabling the MRFIC2001 can be done with its TTL/CMOS compatible Enable pin. The trip point is between 1.0 and 2.0 volts. EVALUATION BOARDS Evaluation boards are available for RF Monolithic Inte- grated Circuits by adding a “TF” suffix to the device type.
