Avago intros pair of miniature 0.25W analog variable gain amplifiers for cellular infrastructure apps

SAN JOSE, USA & SINGAPORE: Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, announced the addition of two miniature 0.25-Watt analog variable gain amplifiers to its broad portfolio of amplifier products for use in cellular infrastructure applications.

Housed in a compact 5 mm by 5 mm by 1.1 mm, 10-lead module package, Avago’s ALM-80110/80210 variable gain amplifiers feature a common footprint for easy integration into most base station designs. Additionally, these amplifiers offer high linearity and dynamic range performance and support all major cellular bands in North America, Europe and Asia.

The ALM-80110 operates from 0.4 to 1.6 GHz, while the ALM-80210 operates from 1.6 to 2.7 GHz and are ideal for use in WLL, WLAN, transmitter receiver gain control, and temperature compensation circuitry applications. Both amplifiers provide an exceptionally high Output 3rd Order Intercept Point (OIP3) level of 40 dBm, which is maintained over a wide attenuation range. Additionally, these devices feature a wide gain control range, low power consumption, as well as excellent input and output return loss.

Avago’s ALM-80110/80210 variable gain amplifiers incorporate a unique solution which integrates Avago’s high linearity 0.25W amplifiers and silicon PIN diode-based pie attenuator into a miniature multiple-chips-on-board (MCOB) module package.

Both of these amplifiers feature broadband fully-matched input and pre-matched output for ease of use and require a minimum amount of external RF matching components. Moreover, the high linearity and dynamic range performance of these amplifiers is achieved through the use of Avago’s proprietary 0.25 um GaAs enhancement-mode pHEMPT process and low distortion silicon pin diode technologies.

Avago intros two new balanced LNAs for cellular infrastructure apps

SAN JOSE, USA & SINGAPORE: Avago Technologies, a leading supplier of interface components for communications, industrial and consumer applications, announced two ultra-low noise, high gain, high linearity Gallium Arsenide (GaAs) balanced low noise amplifiers for cellular infrastructure applications.

Avago’s MGA-16516/17516, which are the latest additions to its family of economical, easy to use LNAs, helps to significantly improve the sensitivity and dynamic range of cellular infrastructure applications.

Both LNAs feature a compact footprint and are designed to be used as first stage LNAs. Typical applications include cellular base station transceiver radio cards, tower mounted amplifiers, combiners, repeaters and remote/digital radio heads.

Avago’s MGA-16516/17516 LNAs are housed in a 4 mm by 4 mm by 0.85 mm surface mount 16-lead QFN package, and were developed using Avago’s proprietary 0.25 m GaAs enhancement-mode pHEMT process.

The MGA-16516 operates from 500 to 1,700 MHz, while the MGA-17516 operates from 1,700 to 2,700 MHz. These new LNAs will enable Avago to provide support for GSM, CDMA, UMTS and next generation LTE cellular bandwidths.

The MGA-16516/17516 have been designed to be used with 3dB hybrid couplers at the input and output of LNAs typically found in the front end of cellular base stations, combiners and transceiver radio cards.

In a typical operating environment of 5-Volts and 50mA per channel, the MGA-16516 delivers a 0.45 dB noise figure, 17.5 dB gain, 11.5 dBm input Third Order Intercept Point (IIP3), and 18 dBm output power at 1 dB compress point (P1dB) at 850MHz.

Under the same operating conditions, the MGA-17516 delivers enhanced performance of 0.52 dB noise figure, 17.2 dB Gain, 13.7 dBm IIP3, and 21.5 dBm output power at P1dB at 1,850 MHz.
