Features
Integrated Mixer, LO Buffer and Output Amplifier 8 dB Conversion Gain 15 dB Image Rejection +11 dBm P1dB +6 dBm LO Drive Level -12 dBm LO Leakage Power
Mimix Broadband's 10.0-18.0 GHz GaAs MMIC transmitter provides +11 dBm output P1dB compression and 15 dB image rejection across the band. This device is an image reject, balanced mixer followed by a two stage output amplifier. The image reject mixer reduces the need for unwanted sideband filtering before the power amplifier. I and Q mixer inputs are provided and an external 90 degree hybrid is required to select the desired sideband. This device comes in a 7x7mm QFN surface mount laminate package which is RoHS compliant. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
