Vector multipliers cut basestation costs
The MAX204x family of vector multipliers is specifically designed for the demanding requirements of GSM/DCS/PCS/Edge, iDEN, PHS, CDMA and 3G linearised power amplifiers for cellular basestations.
The MAX204x family of highly integrated vector multipliers is specifically designed for the demanding requirements of GSM/DCS/PCS/Edge, iDEN, PHS, CDMA and 3G linearised power amplifiers for cellular basestations These devices have a 12dB gain-control range and a 360-degree phase-control range

Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
Gain and phase flatness performance is outstanding, yielding +/-0.25dB and +/-0.25 degrees, respectively.
Exceptional constant group-delay performance over a 260MHz control signal bandwidth yields improved ACLR performance.
In addition, the MAX204x family provides the reliability and ESD robustness that only a silicon-based (SiGe) process can deliver.
With their high switching speed, these devices are tailored for both feed-forward and hybrid digital predistortion-based designs.
An on-chip RF gain amplifier provides 8dB of gain, eliminating the need for an expensive external amp.
To simplify interfacing, the MAX204x family has both current- and voltage-mode inputs.
The MAX2045/MAX2046/MAX2047 are packaged in compact 5 x 5mm 32-pin QFN packages.
Prices start at $8.93 (1000-up, FOB USA).
