RF amplifiers take ESD protection
onboard
Intersil has introduced six new RF amplifiers in its ISL550xx family for use in satellite receivers and ISM (industry, scientific and medical) band applications.
Intersil has introduced six new RF amplifiers in its ISL550xx family for use in satellite receivers and ISM (industry, scientific and medical) band applications The amplifiers have integrated ESD (electrostatic discharge) protection up to 3kV human body model, and are available in multiple impedance options to eliminate the need for costly matching networks

Programmable up-converter simplifies basestations
Intersil has added a new highly integrated quad up-convertor to its CommLinkT family of digital radio ICs for fixed basestation applications.
Intersil's ISL55005 is a 3.3V gain block optimised for operation from 900MHz to 2.5GHz.
The device provides gain of 17dB and an OIP3 (output third-order intercept point) of 18dBm.
It has an input impedance of 75ohm and an output impedance of 50ohm, thus eliminating the need for the system designer to include an impedance translation.
With an ESD rating that is far superior to that of any of its competitors, the ISL55005 provides significant cost savings by reducing the need for external ESD protection.
All of the devices in the ISL550xx family are self-biased and are available in 6-pin SC70 packages.
Gain is constant to 1dB across 1GHz of bandwidth.
They draw very little quiescent current (around 20mA for ISL55005/7/8 and only 13mA for ISL55009/10/11).
The devices also come in 50ohm/50ohm and 75ohm/75ohm input/output impedance configurations.
"Most RF gain blocks on the market do not specify an ESD rating", said Sameer Vuyyuru, Director of Intersil's Standard analogue products group.
"Intersil's ISL550xx family is tested and guaranteed to 3kV".
"This critical feature, along with the self-biasing architecture and multiple impedance options, make these devices extremely easy to use in the ISM band or in satellite receivers and LNBs (low-noise block down-convertors)".
The ISL55005, ISL55007, ISL55008, ISL55009, ISL55010 and ISL55011 are available now in 6-pin SC-70 packaging and are priced at $0.65 in 1000-unit quantities.
