6 TO 18 GHz ENHANCED IMAGE REJECTION MIXERS
MODELS: IRE0618LI1A, IRE0618LI1B AND IRE0618LI1C
FEATURES
• RF/LO coverage ................ 6 to 18 GHz
• LO power range ................ +13 to +15 dBm
• Conversion loss................ 8 dB typical
• Image rejection ................. 35 dB typical
• Packaging.......................... Hermetically sealed
MITEQ’s Model IRE0618LI1 enhanced image rejection mixer utilizes a unique architecture developed to provide
greater than 30 dB of image rejection across multioctave bands. This design inherently suppresses image fre-
quencies by an additional 15 dB over conventional image rejection mixers without the need for phase and ampli-
tude alignment during production test, thereby allowing for consistent reliable performance throughout production.

GENERAL NOTE
1. Unit normally aligned for operation with LO > RF.
If LO < RF is desired, please specify at time of order.
Operation at both modes is a special option with
some degradation in performance.
NOTE:
Test data supplied at 25°C; conversion loss, LO-to-RF isolation and image rejection.
