MICRF112 Datasheet Ask/fsk Transmitter

Manufacturer: Micrel Semiconductor

Overview: MICRF112 300MHz to 450MHz, +10dBm, 1.8V to 3.6V, ASK/FSK Transmitter with Shutdown.

General Description

The MICRF112 is a high-performance, easy to use, true “Data-In, RF-Out,” ASK/FSK, phase-locked loop (PLL) based, transmitter IC for applications in the 300MHz to 450MHz frequency range.

These applications include remote keyless entry (RKE) and tire pressure monitoring (TPMS).

The device needs only a low-cost crystal to precisely set the desired RF frequency, and a few external ponents for matching the power amplifier output to the antenna.

Key Features

  • a low-power shutdown mode in which the device typically consumes 50nA of supply current. This makes it an ideal solution for battery powered applicati.
