Crane Aerospace & Electronics IQ Modulators, Demodulators, and Complex Mixers IQF-20E-70 SQ

The IQF-20E-70 SQ is a space-qualified, high-reliability IQ demodulator in a flatpack package, designed to produce quadrature-phased signals from RF and LO inputs. It operates with an RF frequency range of 70 ± 7 MHz and an LO/RF bandwidth of 70 MHz. The device exhibits a phase balance of 90° ± 2°, an amplitude balance of 0.2 dB, and a conversion loss of 10 dB typical with a maximum of 12 dB. It supports RF power levels up to 0 dBm and LO power levels of +10 to +13 dBm, with a 50 ohm nominal impedance and VSWR of 1.3:1 typical. The operating temperature range is -55°C to +85°C, and it meets the space qualification requirements of Merrimac document CENG-0001.
