The document describes the application of MAX2410 in time-division-duplex communication systems. The product is an RF front-end device that operates in the frequency range around 1.9GHz. It includes a low-noise amplifier (LNA), a downconverter mixer, a local-oscillator (LO) buffer, an upconverter mixer, and a variable-gain power-amplifier (PA) driver. The product features low power consumption, low noise, and high gain.
The MAX2410 performs the RF front‑end transmit/receive function in time‑division‑duplex (TDD) communication systems. It integrates a low‑noise amplifier, down‑converter mixer, local‑oscillator buffer, up‑converter mixer and a variable‑gain power‑amplifier driver in a compact surface‑mount package.
The device operates from a 2.7 V to 5.5 V supply, consumes only 60 mW in receive mode and 90 mW in full‑power transmit, and offers a 35 dB gain‑control range with low noise figures, making it suitable for DECT, PCS, ISM‑Band and other 1.9 GHz wireless standards.
| Power Consumption (Receive) | 60 mW |
|---|---|
| Power Consumption (Transmit) | 90 mW |
| LNA Noise Figure | 2.4 dB (typical) |
| PA Driver Gain Range | 15 dB to 50 dB (35 dB adjustable) |
| Operating Temperature Range | -40 °C to +85 °C |
| Shutdown Power Consumption | 0.3 µW |
It consumes only 60 mW while receiving.
The LNA provides a typical noise figure of 2.4 dB.
The PA driver gain can be adjusted over a 35 dB range.
