The MAX2062 is a dual 50MHz to 1000MHz high linearity, serial/parallel controlled analog/digital variable-gain amplifier (VGA) manufactured by MAXIM
The MAX2062 is a high‑linearity, dual‑path variable‑gain amplifier that operates from 50 MHz to 1 GHz. Each path includes an analog and a digital attenuator that can be controlled via an SPI‑compatible interface or a 5‑bit parallel bus, with four rapid‑fire pre‑programmed attenuation states for fast gain selection. The device can be powered from a single +5 V supply (or +3.3 V for reduced performance) and is offered in a 48‑pin TQFN‑EP package.
The datasheet provides absolute maximum ratings, DC and AC electrical characteristics for both 5 V and 3.3 V supplies, recommended operating conditions, and typical performance graphs such as gain, noise figure, and isolation. Ordering information, package outlines, and revision history are also included.
| Frequency Range | 50 MHz – 1000 MHz |
|---|---|
| Total Attenuation Range | 64 dB |
| Small‑Signal Gain (3.3 V supply) | 18.8 dB |
| Noise Figure (3.3 V supply) | 7.8 dB |
| OIP3 (5 V supply) | +41 dBm |
| Supply Voltage (typical) | 4.75 V – 5.25 V |
| Supply Current (typical) | 148 mA – 210 mA |
| Gain Control Slope (analog) | -13.3 dB/V |
The device operates from a single +5 V supply (typical 4.75 V to 5.25 V) or from +3.3 V for a power‑saving mode.
Four rapid‑fire pre‑programmed attenuation states are supported.
Typical maximum gain is about 19.4 dB at 200 MHz.
