Transceiver for Low Power Radio
The miniature TR1100 transceiver is characterized for operation at data rates from 128 kbps to 1 Mbps using amplitude-shift keyed modulation. The use of a wide dynamic range log detector in the receiver, in combination with digital AGC and a compound data slicer, provide robust channel capture characteristics. Two stages of SAW filtering in the receiver signal path also provide excellent out-of-band interference rejection, and SAW filtering of the transmitter output makes certification of the TR1100 to FCC and Canadian low-power regulations straightforward.
Operating receiver current is 7 mA, transmit current is 6 mA average, and sleep mode current is 1 mA. The TR1100 is designed to operate on a supply voltage of 2.7 to 3.5 V DC. The TR1100 is a six-chip RF hybrid which includes an IC, two SAW devices, and three tuning components. The TR1100 is housed in a ceramic-metal hybrid package that is 0.27 3 0.40 3 0.08 inches in size.
