RF2942 I/Q 915 MHz Transmitter

The RF2942 is a transmitter with a quadrature modulator and power amplifier for use in 915 MH ISM RF products, digital communications and portable mobile devices. 

The main technical features are as follows:

・Operating frequency is 902--928 MHz

・Operating voltage: 2.0～3.6 V

・Operating current is 170～260 mA, standby current is 10～24 mA 

・Output power: 200 mW

・The local oscillator frequency is twice the RF frequency to avoid interference from external synthesizers 

・The quadrature phase of the local oscillator is generated using a passive network inside the integrated circuit 

・The quadrature modulator is driven by a single-ended local oscillator (LO).
