Sequoia Announce, New Ultra Low Profile RF Transceiver IC From Axsem

Sequoia Technology a technology solutions company, with over 25 years expertise, have announced the release of the AX5043, ultra low power RF transceiver IC.

Sequoia Technology - the Berkshire based technology solutions company, with over 25 years expertise in enabling customers bring highly technical products to market, have announced the release of the AX5043, ultra low power RF transceiver IC.


The AX5043 is a single chip narrow -band RF transceiver, configurable to operate from 70MHz - 1.05GHz. With a receiver bandwidth of 1 - 100kHz, the AX5043 offers very long range with a small number of components.

The sensitivity of -126dBm at 868MHz and 1.2kbps FSK is one of the highest sensitivities in the market with only 10.5mA current draw. Together with the excellent power amplifier performance of 17dBm at 55mA current consumption, the AX5043 has the sensational link budget of 143dB. In "Wake on Radio mode", the current consumption is typically below 5uA.

The AX5043 transceiver consists of an integrated RF front end with modulator and demodulator and flexible communication controller. Baseband data processing is implemented in the integrated communication controller for user friendly communication and configuration via an SPI interface. The 256 byte packet buffer in conjunction with the 500nA wake up timer allows the AX5043 to work well together with low cost MCUs. The integrated HDLC protocol guarantees exceptionally compact code and small CPU overhead whilst the digital RSSI provides quick results for low power operation.

David Taylor, Wireless Product Manager comments "The Axsem AX5043 is well suited for applications such as sensor networks, access control systems and automatic meter reading using the Konnex, ARIB or other standards."

Axsem is a fabless semi conductor company specialising in developing cost efficient, mixed signal products for the wireless communication marketplace. Founded in 2000 and headquartered near Zurich, Switzerland, Axsem are one of the market leaders in producing IC's for RF short range devices.
