MAX3537/MAX3538
The MAX3537/MAX3538 broadband RF variable-gain amplifiers (VGA) are designed for digital and OpenCable™ set-tops and televisions. These devices feature a unique design that integrates a dual-band (UHF and VHF) input and a low-noise, variable-gain amplifier. The integrated RF VGA covers a 10MHz to 1GHz input frequency range and provides 22dB of gain-control range.
