19-3445; Rev 1; 6/05 KIT ATION EVALU E L B AVAILA Broadband Variable-Gain Amplifiers General Description Features o Low-Noise VGA Eliminates PIN Attenuator o 22dB Gain-Control Range o Low Noise Figure: 5dB at Maximum Gain Setting o High Linearity: +19dBm IIP3 (MAX3538) at Maximum Gain Setting o Low Power Consumption: <200mW (MAX3537) o Available in a 4mm x 4mm, 12-Pin Thin QFN Package MAX3537/MAX3538 The MAX3537/MAX3538 broadband RF variable-gain amplifiers (VGA) are designed for digital and OpenCableā„¢ 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.
