Maxim has introduced the MAX2029, a high performance, fully integrated, 815 MHz to 1000 MHz SiGe passive mixer.
Designed specifically for 2,5G/3G wireless-infrastructure applications, it delivers an impressive combination of linearity, noise performance and component integration.
When configured as an up-converter, this single IC provides 39 dBm of IIP3, 71 dBc of LO ±2IF suppression, and a conversion loss of only 6 dB. As a down-converter, it delivers 36,5 dBm of IIP3, 27 dBm of P1dB, 6,5 dB of conversion loss, and a 6,7 dB noise figure. In addition, it exhibits excellent second- and third-order spurious suppression. The IC is ideal for 815 MHz to 1000 MHz 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-/down-converter, the MAX2029 integrates a double-balanced mixer core with an LO amplifier, two baluns, an LO switch, plus dozens of discrete components. This integration is said to reduce the total board space used by the mixer by 40%, and to reduce the discrete part count by 33%. The 2RF-2LO performance of 72 dBc (with a -10 dBm RF tone) also eases the filtering requirements of close-in harmonics, thus enabling simpler and more cost-effective filter designs.
This mixer offers a wide, DC to 250 MHz IF frequency range with a 570 MHz to 900 MHz, low-side LO injection range. It supports frequency hopping with an integrated SPDT LO switch that has switching speeds of less than 50 ns and 53 dB of LO1-to-LO2 isolation. The on-board 0 dBm drive, LO buffer provides ±3 dB drive-variance control, ensuring stable gain, NF, and IIP3 performance over temperature, supply and input power. The chip has gain-variation performance of ±0,2 dB over the -40°C to +85°C temperature range, while the IIP3 spread is +0,4 dB/-0,6 dB over the temperature range.
