VMMK-3503 Amplifier

Description

The VMMK-3503 is a small and easy-to-use, broadband, variable gain amplifier operating in various frequency bands from 0.5-18 GHz. It is housed in the Avago Technologies’ industry-leading and revolutionary sub-miniature chip scale package (GaAsCap wafer scale leadless package) which is small and ultra thin yet can be handled and placed with standard 0402 pick and place assembly
equipment. The VMMK-3503 provides maximum gain of 12 dB with a typical gain range of 23 dB where the gain control is accessed from the input port by way of a large value external resistor. It can be operated from 3 V to 5 V power supply. It is fabricated using Avago Technologies unique 0.25 μm E-mode PHEMT technology which eliminates the need for negative gate biasing voltage.
