Forefront RF products expand the global market reach of smartphones, wearables and IoT devices by simplifying their design.

Forefront RF simplify RF Front End design using self-interference cancellation

For decades, mobile phones have relied on ultra-high Q SAW and BAW piezo crystal filters to separate their transmit and receive signals. With the advent of 5G, the sheer number of filters required makes this convention untenable.  

Forefront RF has a better way – self-interference cancellation

Forefront’s Adaptive Passive Cancellation technology uses software control to maintain the accuracy of unique passive RF cancellation circuits enabling the receiver to “hear” the weakest signals while transmitting at full power. The APC circuits operate over a wide frequency range removing the need for a bank of switched SAW and BAW crystal filters. 

Forefront RF’s products will simplify the design and development of the RF front end in 4G and 5G phones, dramatically reducing the space needed in the phone.
