2 TO 26 GHz IMAGE REJECTION MIXERS
MODELS: IRBA0226LC1A, IRBA0226LC1B AND IRBA0226LC1C
FEATURES
• RF/LO coverage ................ 2 to 26 GHz
• IF operation ....................... 20 to 200 MHz
• LO power range ................ -10 to +13 dBm
• Conversion gain ............... 20 dB typical
• Image rejection ................. 20 dB typical
• Biasable
Image rejection mixers are useful for wideband test equipment or ultra-broadband receivers requiring rejection of
an unwanted sideband of signal or noise following a low-noise front-end amplifier. These mixers are also useful
as linear single-sideband upconverters by operating in the reverse mode. The MITEQ IRBA Series design utilizes
two mixers with biasable bridge diode quads, thus allowing operation at very low LO powers. An integrated IF
amplifier also makes the unit’s sensitivity less dependent on load noise and mismatch.
