SUNNYVALE, CA—January 22, 2008—Maxim Integrated Products (Pink Sheets: MXIM) introduces the MAX2029, the industry's highest performance, fully integrated, 815MHz to 1000MHz SiGe passive mixer. Designed specifically for 2.5G/3G wireless-infrastructure applications, the MAX2029 delivers an unparalleled combination of linearity, noise performance, and component integration. When configured as an upconverter, this single IC provides 39dBm of IIP3, 71dBc of LO ±2IF suppression, and a conversion loss of only 6dB. As a downconverter, the MAX2029 delivers equally impressive performance with 36.5dBm of IIP3, 27dBm of IP1dB, 6.5dB of conversion loss, and a 6.7dB noise figure. In addition, it exhibits excellent 2nd- and 3rd-order spurious suppression. The MAX2029 is ideal for 815MHz to 1000MHz WCDMA, GSM850/GSM900 EDGE, cdma2000®, and iDEN® base-station applications in which high linearity and a low noise figure are critical for enhanced receiver and transmitter performance.
As a complete SiGe up-/downconverter, the MAX2029 integrates a state-of-the-art, double-balanced mixer core with an LO amplifier, two baluns, an LO switch, 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 MAX2029's outstanding 2RF-2LO performance of 72dBc (with a -10dBm RF tone) also eases the filtering requirements of close-in harmonics, thus enabling simpler and more cost-effective filter designs.
This mixer offers an exceptionally wide, DC to 250MHz IF frequency range with a 570MHz to 900MHz, low-side LO injection range. It supports frequency hopping with an integrated SPDT LO switch that has switching speeds of < 50ns (typ) and 53dB of LO1-to-LO2 isolation. The on-board 0dBm drive, LO buffer provides ±3dB drive-variance control, thus ensuring stable gain, NF, and IIP3 performance over temperature, supply, and input power. The MAX2029 has excellent gain-variation performance of ±0.2dB over the -40°C to +85°C industrial temperature range. The IIP3 spread is similarly impressive at +0.4dB/-0.6dB over temperature.
The MAX2029 is packaged in a compact, 5mm x 5mm, 20-pin TQFN. The package is pin compatible with the MAX2039/MAX2041/MAX2042*/MAX2044* series of 1700MHz to 2200MHz, 1700MHz to 3000MHz, 2300MHz to 2700MHz, and 3200MHz to 3900MHz mixers, making this entire family of passive upconverters and downconverters ideal for applications in which a common PC-board layout is used for multiple wireless-infrastructure frequency bands. Lead-free packaging is also available. Prices start at $6.15 (1000-up, FOB USA).
Maxim Integrated Products, a two billion dollar company, designs and manufactures ICs for analog and mixed-signal applications. The company's broad portfolio of 27 product lines is among the industry's deepest, with over 5400 products.
