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 Agilent MiniPak measures only 1.4 x 1.2 x 0.7mm and takes up 60% less board space than the conventional 2.1 x 2.0 x 0.9mm SC-70 package.
Applications for the Agilent ATF-551M4 include 802.11a or 802.11b wireless LAN PC cards, fixed wireless infrastructure in the 2.4, 3.5 and UNII (5GHz) bands, and handsets where the smallest possible components are required.
The Agilent ATF-331M4 device is particularly useful as a low-noise amplifier for basestation receivers.
The 400-micron ATF-551M4 is a single-voltage E-pHEMT GaAs FET that does not need a negative gate bias voltage for operation.
The device's exceptional low noise performance (minimum noise figure is less than 1dB from 450MHz to 6GHz) and low power consumption makes it highly suitable as a low-noise amplifier for wireless receiver applications in the 2 to 10GHz frequency range.
Typical low current performance of the ATF-551M4 at 2GHz (2.7V, 10mA) includes: 0.5dB noise figure, +24.1dBm third-order output intercept point (OIP3), +14.6 dBm output power at 1dB gain compression (P1dB) and 17.5dB associated gain.
At 5.8GHz (2.7V, 10mA) the transistor offers 0.9dB minimum noise figure, +24.5dBm OIP3, +14.3 dBm P1dB and 12dB associated gain.
The 1600-micron ATF-331M4 is a dual-voltage PHEMT based on Agilent's advanced process.
The device's combination of high linearity and low noise figure is optimised for the design of the first or second stage of a basestation LNA.
Typical performance at 2GHz (4V, 60mA) is 0.6dB NF, +31dBm OIP3, +19dBm P1dB and associated gain of 15dB. Request a free brochure from Avago Technologies ...
