The 2751 is a 900 MHz ISM band radio front-end intended for use in half duplex radio applications such as cordless phones and FCC Part 15 compliant devices. It integrates a power amplifier (PA), a Low Noise Amplifier (LNA), Pin Diode drivers for an external transmit/receive switch, and control circuits. The 100mW power amplifier has output power control with a >20dB range. The ML2751 can be used to increase battery life and offers output power ramp control in TDMA applications. An internal LNA eliminates the need for a discrete design. PIN diode drivers control the transmit/receive switch directly. Internal logic individually enables the LNA, PA, and PIN diode drivers. A power down mode to minimize current consumption is included.
