Maxim claims its MAX2056/MAX2057 are the industry's highest performing RF variable gain amplifiers (VGAs) in monolithic form. Designed specifically for 2,5 G/3 G wireless-infrastructure applications, the devices deliver over 40 dB of linearly-controlled dynamic range while maintaining up to 39 dBm of OIP3 and 64 dBm of OIP2 over all attenuation settings.
These VGAs are intended for 800 to 1000 MHz/1700 to 2500 MHz (respectively) WCDMA, GSM/DCS/PCS/EDGE, cdma2000, iDEN and WiMAX wireless infrastructure applications where high linearity and low noise figure are critical for maintaining high levels of ACLR and EVM transmitter performance. These capabilities also enhance receiver sensitivity and blocker immunity when the MAX2056/MAX2057 are used as IF VGAs within WiMAX and microwave terrestrial-link applications.
As complete SiGe VGAs, they integrate two state-of-the-art, voltage-variable attenuators with a low-noise, high-linearity two-stage RF amplifier. The analog attenuators yield infinite control and high attenuation accuracy over selectable 22 dB or 44 dB control ranges. Cascading one attenuator of the MAX2056 low-band VGA with the on-chip amplifier yields 15,5 dB of gain, a noise figure of 4,5 dB, an OP1 dB of 23,5 dBm, and an OIP3 level of 39 dBm. The MAX2057 high-band version similarly offers 15,5 dB of gain, a noise figure of 6 dB, an OP1 dB of 23,8 dBm, and an OIP3 level of 37 dBm.
