Description
The BT1074Bi is a BiCMOS monolithic integrated RF transceiver. In addition to the input I/Q interface, the
IC contains all of the required components to implement a complete RF-IF transceiver. This includes two
on-chip local oscillators, a low noise amplifier with an overall noise figure of less than 5dB over tempera-
ture and power supply variations, two highly linear down-conversion mixers, an IF amplifier, an upconver-
sion mixer and an on-chip power amplifier capable of delivering -4dBm to +17dBm. The unit operates with
a power supply voltage range of 2.7 - 3.6 volts.
* See Single-ended RFM input application example on page 15.
