TDA5101数据手册RF/IF射频/中频RFID的射频发射器规格书PDF

描述 Description

General Description
The TDA5101A is a single chip ASK transmitter for the frequency band 315 MHz. The IC offers a high level of integration and needs only a few external components. The device contains a fully integrated PLL synthesizer and a high efficiency power amplifier to drive a loop antenna. A special circuit design and an unique power amplifier design are used to save current consumption and therefore to save battery live. Additionally features like a power down mode, a low power detect and a divided clock output are implemented.
