Device Overview
General Description
The IQ-1545 is a passive IQ mixer. This broadband mixer spans 1.5 to 4.5 GHz on the RF and LO ports with an IF from DC to 500 MHz. Up to 25 dB of image rejection is available due to the excellent phase and amplitude balance of its LO quadrature hybrid. IQ series mixers have generally been replaced with MMIQ mixers with superior performance, repeatability, and availability. IQ series mixers are still used in legacy systems and are suitable for laboratory use.
Features
- LO/RF 1.5 to 4.5 GHz
- IF DC to 500 MHz
- 5.5 dB Typical Conversion Loss
- 43 dB Typical LO to RF Isolation
- 3 degree Typ Quadrature Phase Deviation
- .3 dB Typical Amplitude Deviation
