The BLP25RFE001 is designed for RF energy applications such as industrial heating, defrosting and/or cooking and plasma lighting and described by Ampelon as an ‘all-in-one solution’ for RF signal generation operating from a single 3.3 VDC supply.
The IC is assembled in a miniature HVQFN28 and occupies little PCB space. The device delivers an output power up to 24dBm from the on-chip medium power amplifier and is software controllable across a SPI bus. A low power amplifier provides a separate output up to 7dBm.
The BLP25RF001 incorporates a 360-degree phase shifter that can be programmed in steps of 1.4-degree increments. While daisy chaining of the device allows coherent excitation of multiple RF amplifier chains at different phases.
The signal generation also features a 20dB gain control, an integrated RF switch for PWM control, and a readable temperature sensor that measures the junction temperature of the die.
