Plessey unveils 3 to 6 channel rf power splitter
1 min read
Plessey Semiconductors has announced the introduction of its PS12000 3/6 channel dc to 2GHz power splitter. The PS12000 is built on Plessey's 20GHz complementary bipolar process and is said to provide a highly linear power splitter for broadband rf or video signals.
The device is a broadband rf power splitter that can provide either three differential output signals or six single ended outputs. The input signal is initially boosted through a high linearity 6dB gain buffer before being split to the three differential output drivers. Two of these output drivers include a 0 to -40dB AGC stage allowing signal levels to be adjusted as required or effectively switched off. The datasheet describes in detail how the various input and output signals can be matched to meet individual system needs including 75 or 50Ohm.
It features broadband operation up to 2GHz, linearity of 20dBm IIP3 and 50dBm IIP2, an 8dB noise figure and >40dB AGC range. Gain tracking error is <1dB.
The PS12000 is offered in a 28lead MLP package; samples are available now and the part will be in volume production from April. The device is supported by a datasheet and an evaluation board is available on request.
