Linear Technology introduced the LTC5542 1.6GHz to 2.7GHz High Dynamic Range Downconverting Mixer .
LTC5542 is part of a family of high dynamic range passive downconverting mixers designed by Linear Technology and is covering the 700MHz to 4GHz frequency range.
High Dynamic Range Downconverting Mixer Family designed by Linear Technology is :
PART RF RANGE LO RANGE
LTC5540 600MHz –1.3GHz 700MHz – 1.2GHz
LTC5541 1.3GHz – 2.3GHz 1.4GHz – 2.0GHz
LTC5542 1.6GHz – 2.7GHz 1.7GHz – 2.5GHz
LTC5543 2.3GHz – 4GHz 2.4GHz – 3.6GHz
The LTC5542 is optimized for 1.6GHz to 2.7GHz RF applications.
A typical application for LTC5542 is a LTE or WiMAX receiver with a 2.3GHz to 2.7GHz RF input and low-side LO.
The LTC5542 designed to operate from 3.3V supply but the IF amplifier can be powered by 5V for the highest P1dB.
Main features of the LTC5542 downconverting mixer are : Conversion Gain 8dB at 2.4GHz , IIP3 26.8dBm at 2.4GHz , Noise Figure 9.9dB at 2.4GHz , High Input P1dB , 3.3V Supply , 660mW Power Consumption , Shutdown Pin , 50Ω Single-Ended RF and LO Inputs , High Isolation LO Switch , 0dBm LO Drive Level , High LO-RF and LO-IF Isolation .
