This MMIC can be used as either an up converter or down converter in microwave or millimeter wave applications. If desired, the LO amplier can be biased to function as a frequency multiplier to enable second harmonic mixing of the LO input. The mixer section ofthe AMMC-3040 is fabricated using a suspended metal system to create a unique, broadside-coupled balun structure (patent pending) to achieve exceptional bandwidth. The MMIC provides repeatable conversion loss without tuning, mak- ing it highly suitable for automated assembly processes. For improved reliability and moisture protection, the die is passivated at the active areas. ѕ High IIP3: +23 dBm Wide bandwidth Օ RF: 18-36 GHz LO: 18-36 GHz Օ IF: DC-3 GHz Fundamental or subharmonic mixing Օ Up or down converter Conversion loss: 9.5 dB Օ P1dB: +17 dBm Low LO drive power: +2 dBm Օ Usable to 42 GHz > Point-to-point radio Symbol Parameters/Conditions Units Min.

Biasing for Sub-Harmonic Mixing The LO amplier in the AMMC-3040 can also be used as a frequency doubler. Optimum conversion eciency as a doubler is obtained with an input power level of 3 to 8 dBm.Frequency multiplication is achieved by reducing the bias on the rst stage FET to eciently generate har- monics. The remaining three stages are then used to provide amplication. While many bias methods could be used to generate and amplify the desired harmonics within the AMMC- 3040s LO amplier, the following information is sug- gested as a starting point for subharmonic mixing applications....
