The TRF3701 and TRF3702 are low noise quadrature direct modulators capable of modulating complex input signals up to radio frequency (RF).
Both devices are optimised for use in direct up conversion architectures where space and cost savings are key requirements.
The devices accept inputs from baseband up to intermediate frequency of 250MHz.
The signals are then up-converted up to 1.5GHz by TRF3701 or up to 2.5GHz by TRF3702.
Both devices support the highest output power (+7dBm) and the lowest noise floor (-156dBm/Hz) in the industry.
The TRF3701 is scheduled for release in April 2004 and the TRF3702 is expected to release later this year and can be evaluated using a TRF3701/02 EVM and software.
The devices are pin compatible and are available in 16-pin QFN packages.
The TRF3750 is a monolithic phase lock loop (PLL) synthesiser optimised for low noise performance, a key factor in digital mobile communication.
When used with a voltage-controlled oscillator (VCO), the TRF3750 can generate frequencies from 100MHz up to 2.4GHz for GSM, UMTS and CDMA applications.
The TRF3750 is released to production now and can be evaluated using the TRF3750 EVM and software.
It is available in a 16-pin TSSOP.
