Modulators that boost capacity

Skyworks RF mixer demod

Skyworks Solutions have introduced three wideband fixed-gain quadrature modulators for cellular infrastructure and high-performance radio-link applications. These modulators – the SKY73077, SKY73078 and SKY73092, have been designed to support the leading providers of 3G and 4G base stations.

As network demand inevitably continues to increase in years to come, mobile operators will need to upgrade and expand existing networks in order to acquire more analogue and mixed-signal content and avoid network traffic jams. The addition of quadrature modulators will support increased network capacity and better performance.

Accuracy and balance

The phase accuracy and amplitude balance of Skyworks’ new modulators, supplied by Acal BFi, ensure high performance for multi-carrier communications systems.

They have:

  • 500 MHz-plus 3db modulation bandwidth
  • low noise floor, and
  • wide operating frequency range.

Unrivalled expertise

By working closely with the leading component manufacturers in the UK and abroad, we can supply you with the best equipment and help you get the best out of your purchases.

Acal BFi engineers take part in training run by the companies whose products we supply, giving us unequalled product knowledge backed up by technical know-how.

Product details

  RF output frequency range (MHz) Broadband noise floor (dBm/Hz)
SKY73077 1,500 to 2,700 -158
SKY73078 500 to 1,500 -158
SKY73092 400 to 6,000 -161

All three modulators are designed to convert complex baseband IF signals directly up to RF. These modulators contain high linearity, excellent I/Q phase accuracy and amplitude balance. They accept two differential baseband inputs and a single-ended local oscillator, and generate a single-ended RF output.
