2300MHz to 4000MHz SiGe passive mixer for LTE, WiMAX, and MMDS

The analog semiconductor expert Maxim has introduced MAX2044, 2300MHz to 4000MHz SiGe passive mixer. Designed specifically for LTE, WiMAX, and MMDS wireless-infrastructure applications.

The MAX2044 in down converter configuration provides 32.5dBm of IIP3, 21dBm of IP1dB, 7.7dB of conversion loss, and an 8.5dB noise figure. MAX2044 features high level of 2nd- and 3rd-order spurious suppression. As an upconverter, the MAX2044 delivers 33.5dBm of IIP3, 60.2dBc of LO ±2IF suppression, and a conversion loss of only 7.7dB. MAX2044 is strongly suggested for demanding base-station applications where high linearity and a low noise figure are critical for enhanced receiver and transmitter performance. The device supports both high- and low-side LO injection architectures for 3.1GHz to 3.9GHz LTE and WiMAX base stations; the MAX2044 can be configured for 2.3GHz to 2.9GHz LTE, WiMAX, and MMDS high-side injection architectures as well.

As a complete SiGe up-/downconverter, the MAX2044 integrates double-balanced mixer core with an LO amplifier and two baluns, plus dozens of discrete components. The MAX2044 offers 2RF - 2LO performance of 68dBc (with a -10dBm RF tone) to ease the filtering requirements of close-in harmonics.
