Up-/Down-Converting SiGe Mixer covers LTE/WiMAX/MMDS applications.
Press Release Summary:
Supplied in 5 x 5 mm TQFN package, passive MAX2044 supports high- and low-side LO injection architectures for 3.1-3.9 GHz LTE and WiMAX base stations. It can also be configured for 2.3-2.9 GHz LTE, WiMAX, and MMDS high-side injection architectures. As downconverter, IC provides 32.5 dBm of IIP3, 21 dBm of IP1dB, 7.7 dB conversion loss, and 8.5dB noise figure. When configured as upconverter, it delivers 33.5 dBm of IIP3, 60.2 dBc of LO ±2IF suppression, and conversion loss of 7.7 dB.
Original Press Release:
Highest Linearity, Up-/Downconverting, 2300MHz to 4000MHz SiGe Mixer for LTE, WiMAX, and MMDS Base Stations
2300MHz to 4000MHz, SiGe passive up-/downconverting mixer integrates LO buffer.
Maxim's new up-/downconverting SiGe passive mixer sets new benchmarks for linearity, noise performance, and component integration.
SUNNYVALE, CA-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX2044, the industry's highest performance, fully integrated, 2300MHz to 4000MHz SiGe passive mixer. Designed specifically for LTE, WiMAX(TM), and MMDS wireless-infrastructure applications, the MAX2044 delivers an unparalleled combination of linearity, noise performance, and component integration over an exceptionally wide band of operation. When configured as a downconverter, this single IC provides 32.5dBm of IIP3, 21dBm of IP1dB, 7.7dB of conversion loss, and an 8.5dB noise figure. In addition, it exhibits excellent 2nd- and 3rd-order spurious suppression. As an upconverter, the MAX2044 delivers equally impressive performance with 33.5dBm of IIP3, 60.2dBc of LO ±2IF suppression, and a conversion loss of only 7.7dB. The combination of these parameters makes the MAX2044 ideal 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 a state-of-the-art, double-balanced mixer core with an LO amplifier and two baluns, plus dozens of discrete components. This integration reduces the total board space used by the mixer by 40%, and reduces the discrete part count by 33%. The MAX2044's outstanding 2RF - 2LO performance of 68dBc (with a -10dBm RF tone) also eases the filtering requirements of close-in harmonics, thus enabling simpler, more cost-effective filter designs.
The MAX2044 is packaged in a compact, 5mm x 5mm, 20-pin TQFN that is pin similar to both the MAX2029/MAX2031/MAX2032 650MHz to 1000MHz mixers and the MAX2039/MAX2041/MAX2042 1700MHz to 3000MHz mixers. This entire family of passive up-/downconverters is, therefore, ideal for applications in which a common PC-board layout is used for multiple frequency bands. Prices start at $5.95 (1000-up, FOB USA).
