Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC5543IUH is a high dynamic range passive downconversion mixer optimized for radio frequency (RF) applications from 2.3GHz to 4GHz. The mixer's local oscillator (LO) frequency must be in the 2.4GHz to 3.6GHz range for optimal performance. The LTC5543IUH is designed for 3.3V operating voltage, but the intermediate frequency (IF) amplifier can be powered by 5V voltage for higher P1dB performance ‌.

The LTC5543IUH has the following features:

Conversion gain: 8.4dB (at 2500MHz)

IIP3:24.5dBm (at 2500MHz)

Noise Index: 10.2dB (at 2500MHz)

17.5dB NF at +5dBm blocking signal

High input P1dB

3.3V power supply, 660mW power consumption

With stop pin

50Ω single-ended RF and LO inputs

LO Input 50Ω match (when down)

High isolation LO switch

0dBm LO Drive level

High LO-RF and LO-IF isolation

Small solution form factor

20 pin (5mm x 5mm) QFN package
