Avago Technologies has introduced the MGA-63xP8 low-noise amplifiers (LNAs) and ALM-11x36 fail-safe bypass LNA modules which it said offer improved receiver sensitivity for base transceiver stations and tower mounted amplifiers applications.
The MGA-63xP8 LNA series integrates active bias circuitry and a power down function. Its operational bandwidth is 700-2600MHz, with the MGA-636P8 device operating from 450-1500MHz, while the MGA-637P8 and MGA-638P8 operate from 1500-2500MHz and 2500-4000MHz, respectively.
Designed for the GSM, CDMA and UMTS, as well as the next-generation LTE bands, the LNAs are housed in a common footprint miniature package measuring 2.0 by 2.0 by 0.75 mm.
The ALM-11x36 LNA modules are equipped with a fail-safe bypass function, which is designed for TMA applications to enable the LNA bidirectional bypass path during the absence of DC power supply.
All matching components are integrated within the modules and the 50 ohm RF input and output pins are already internally AC-coupled.
The ALM-11036 module covers 776-870MHz, the ALM-11136 module covers 870-915MHz, the ALM-11236 module covers 1710-1850MHz and the ALM-11336 module covers 1850-1980MHz.
All the modules share the same 7.0 x 10.0 x 1.5mm package and pin out configuration.
