mode states to achieve excellent power-added efficiencies at low-range and mid-range output power levels and have a quiescent current of less than 4 mA.
In a 3 mm by 3 mm footprint, the devices display very good linearity at maximum output power and feature internal voltage regulation. They also have an integrated “daisy chainable” directional RF coupler with 20dB directivity.
GaAs pHEMT SP3T switch for communication systems
A new high performance gallium arsenide device has been revealed by RFMD
RFMD’s new RFSW6131 is a GaAs pHEMT Single- Pole Three-Throw (SP3T) switch designed for use in Cellular, 3G, LTE, and other high performance communications systems.
The device is suited to cellular, 3G, LTE infrastructure applications and WiBro, WiMAX, LTE. It can also be used in wireless backhaul and in GMSK, QPSK, DQPSK and QAM modulation.
The RFSW6131 is currently available in production quantities. Pricing begins at $0.60 each for 1000 pieces.
RFMD reveals InGaP/ GaAs 2.5GHz to 2.7GHz FEM
The FEM uses the firm’s indium gallium phosphide and gallium arsenide technologies
RFMD has introduced the new RFFM7600 FEM for 2.5GHz to 2.7GHz LTE/WiMAX.
The Front End Module (FEM) employs the firm’s proprietary InGaP HBT and GaAs pHEMT technologies.
RFSW6131
The device has a symmetric topology and RFMD boasts that it offers excellent linearity and power handling capability. The module is 3V and 5V positive logic compatible and features LF to 6000MHz operation. At 2GHz , it has a low loss of 0.5dB at and an isolation of 27dB .
The RFSW6131 has a high IP3 of 56dBm P0.1dB: 31dBm (at 5V, and 2.2GHz). and comes in a 1.5mm x 1.5mm package.
