The TR family of ASH transceivers has been introduced for short-range wireless and data link applications.

The TR family of ASH transceivers has been introduced for short-range wireless and data link applications. On the receive side, each transceiver includes a log detector in combination with digital automatic gain control (AGC) in order to achieve 100 dB of dynamic range. The receive side also includes two low-loss surface-acoustic wave (SAW) devices to reduce out-of-band signals.

The receiver can achieve –100 dBm sensitivity at 2.4 kb/s on a current budget of 1.8 mA or –85 dBm sensitivity at 115.2 kb/s on a 4.5 mA current budget. In addition, the receiver features a 1 µA sleep mode that reduces overall current consumption in the transceivers.

On the transmit side, the new transceiver family supports on off keying (OOK) and amplitude shift-keying (ASK) modulation techniques. In addition, the transmitter provides adjustable power and better than –50 dBc harmonics.

Currently, there are two products available in the TR transceiver family. The TR1000 operates in the 916.5 MHz band and is designed for short-range data link applications in North America. The second product, the TR1001, works at 868.35 MHz, making it well suited for short-range wireless apps in the Europe and Scandinavia.
