Integrated VCOs pack in more microwave functions
Now available from Link Microtek is a new range of low-cost, plastic-packaged MMIC voltage controlled oscillators (VCOs) that feature a high level of integrated functionality.
The new device operates as a true duplexer, not only combining the TX signals from the basestations and sending them to a common antenna, but also splitting the RX signals from the antenna and sending them to the respective basestations.
This high-performance unit features a maximum insertion loss of 0.6dB, a minimum band-to-band isolation of 50dB, and a minimum return loss of 18dB.
Suitable for masthead or in-building applications, the UFD21A1721-01 has a power handling capability of 200W (average) or 2.5kW (peak) and is believed to be the smallest such unit on the market at this power level.
Its overall dimensions, excluding connectors, are just 130 x 145 x 46mm.
The duplexer-combiner can be specified with an optional DC feed, which is required for some types of basestation.
