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.
Low-power serial ADC runs up to 200Ksample/s
New from Maxim Integrated Products, the MAX1162 serial-interface 16bit A/D convertor connects directly to SPI, QSPI and Microwire devices without additional interface logic.
This single IC provides 34.5dBm of IIP3, 24.4dBm of IP1dB, 7.3dB of noise figure, and a conversion loss of only 7.1dB.
In addition, the MAX2039 exhibits excellent 2nd- and 3rd-order spurious suppression.
The MAX2039 is ideal for 1700 to 2200MHz W-CDMA/UMTS, DCS/PCS/Edge, cdma2000 and TDMA basestation applications where high linearity and low noise figure are critical for enhanced receiver and transmitter performance.
The device offers an exceptionally wide 40 to 350MHz IF frequency range with a 1400 to 2000MHz low-side LO injection range.
An LO frequency range of 1900 to 2400MHz is also supported by the MAX2041 which has been optimised for high-side LO injection.
As a complete SiGe up- and downconvertor, the MAX2039 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 a factor of 2.5x, and reduces the discrete part count by 33%.
The MAX2039's outstanding 2RF-2LO performance can also ease the filtering requirements of close-in harmonics, thus leading to simpler and more cost-effective filter designs.
Frequency hopping is supported with the integrated SPDT LO switch with switching speeds of less than 50ns and 45dB of LO1-to-LO2 isolation.
The onboard 0dBm drive, LO buffer provides +/-3dB drive-variance control, yielding stable gain, NF and IIP3 performance over temperature, supply, and input power.
The device has excellent gain-variation performance of +/-0.5dB over the -40 to +85C industrial temperature range.
IIP3 spread is similarly impressive at +/-0.75dB over temperature.
The MAX2039 comes in a compact 5 x 5mm, 20-pin thin QFN.
Lead-free packaging is also available.
Prices start at $6.15 (1000-up, FOB USA).
