RFMW, Ltd. announces design and sales support for the Skyworks, Inc. SKY66110-11 BlueTooth Low Energy (BLE) Front-end Module (FEM). The SKY66110-11 transmit section draws 10mA at 10dBm output power in the 2.4GHz frequency range. Low current draw is critical in products using coin cell batteries such as wearables, hearing aids, sensors, etc. Although some transceiver chips have on-board Tx power amplifiers, the addition of the Skyworks BLE FEM can more than double the effective range of some SoCs. And due to the higher efficiency of a dedicated PA, overall system current usage can be decreased by up to 30% while…
RFMW , Ltd. announces design and sales support for XSYSTOR controller modules used for operation and protection of depletion mode transistors. Primarily designed for GaN devices, controllers like the 200X02R0 protect GaN transistors during the power On/Off sequence of internal and external voltage supplies. The 200X02R0 is an inverting controller. A positive analog voltage from a potentiometer, ePOT, or microcontroller is inverted into a unity gain negative voltage for device gate bias. A single supply of 28-65VDC is all that is required. TTL enable for both gate and drain switching are independent or made sequential for stability purposes. The 200X02R0…
