Features
Sub-harmonic Transmitter Integrated IR Mixer, LO Buffer & Output Amplifier +13 dBm P1dB 2.0 dBm LO Drive Level 20.0 dB Image Rejection, 9.0 dB Conversion Gain 7x7 mm, QFN
Mimix Broadband’s 17.0-25.0 GHz GaAs MMIC transmitter has a +13.0 dBm output P1dB and 20.0 dB image rejection across the band. This device is an image reject sub-harmonic anti-parallel diode mixer followed by a balanced two stage output amplifier and includes an integrated LO buffer amplifier. The image reject mixer reduces the need for unwanted sideband filtering before the power amplifier. The use of a sub-harmonic mixer makes the provision of the LO easier than for fundamental mixers at these frequencies.
