Note : Your Quotation Request will be directed to Linear Technology.

The LTC5551 from Linear Technology is an ultrahigh dynamic range RF downconverting mixer for applications require the very best in performance. This down conversion mixer has an RF Frequency range from 300 MHz to 3.5 GHz, a high linearity of 36 dBm IIP3 and a low noise figure of 9.7 dB. The LTC5551 boasts 2.4dB of conversion gain, substantially improving receiver dynamic range and ensures robust radio performance with its high 1dB compression point of 18 dBm. Both the RF and LO inputs have integrated balun transformers, further reducing cost and external components while simplifying integration. The mixer is powered from a single 3.3V supply with current consumption of 204 mA, delivering performance with exceptionally low power. The mixer also has a low power mode controlled via the ISEL pin. In this mode, current consumption drops by 30% to 142 mA, trading off the IIP3 slightly to +29.3 dBm. It is available in a 16 Lead 4 x 4 mm QFN Package. The LTC555 is ideally suited for a wide range of mission-critical, high performance applications that are exposed to strong interference sources such as multi-carrier GSM, 4G LTE and LTE-Advanced multimode basestations, point-to-point backhauls, military communications, wireless repeaters, public safety radios, VHF/UHF/white-space broadcast receivers, radar and avionics.
