Shrinking GaAs FETs maintain performance
to 6GHz
Agilent Technologies reckons its ATF-541M4 is the industry's smallest single-voltage E-pHEMT GaAs FET.
Agilent Technologies reckons its ATF-541M4 is the industry's smallest single-voltage E-pHEMT GaAs FET The Agilent ATF-541M4's miniature leadless package measures only 1.4 x 1.2 x 0.7mm, and so takes up 60% less board space than the conventional SC-70 package (2.1 x 2.0 x 0.9mm)

Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
The device's small size, low noise and high linearity makes it highly suitable for tower-mounted amplifiers and front-end LNAs or hybrid modules for GSM/TDMA/CDMA/W-CDMA basestations operating at 900MHz and 1.9GHz.
Typical performance at 2GHz (3V, 60mA) is 0.5dB noise figure, +35.8dBm OIP3, +21.4dBm P1dB and 17.5dB associated gain.
At 5.8GHz (3V, 60mA) the numbers are 1.2dB Fmin, +37.6dBm OIP3, +19.4dBm P1dB and 11.9dB associated gain.
Agilent's E-pHEMT enhancement mode devices are the first commercially available single-supply GaAs transistors that do not need a negative gate bias voltage for operation.
They can help simplify the design and reduce the cost of receivers and transmitters in many applications in the 450MHz to 6GHz frequency range.
Both the ATF-541M4 and its SC-70-packaged counterpart, ATF-54143, exhibit superior linearity, P1dB and NF performance at higher frequencies, especially notable in the 5 to 6GHz frequency range.
Both can operate effectively as a driver amplifier for 5GHz 802.11a and HiperLAN/2 wireless LAN network interface cards.
As they are designed for optimal RF performance at 3V, they are suitable for operation in PCMCIA-standard PC cards for laptop and handheld computers.
