Aeroflex Corp. introduces the 3065A RF combiner that when used with signal generator and RF digitizer modules from the Aeroflex 3000 PXI range offer high performance, low cost modular test systems for testing RF transceivers and components.

The two-input combiner provides summed signal outputs and supports various combinations of input and output switched path configurations to enable testing of single- and multi-port RF devices without the need to alter connections.

Operating over the frequency range 250MHz to 6GHz, the 3065A provides a combined low loss connection for a RF signal generator and RF digitizer to a mobile phone antenna, while offering high isolation between input ports and accepting input of power levels of up to +33dBm for TDMA burst signals or +30dBm for continuous CW.

The low loss between the unit under test and the digitizer increases overall test system sensitivity, reducing the measurement uncertainty due to noise, and hence enabling more accurate calibration of mobile phone transmitters for UMTS and GSM UEs. The improvement in system sensitivity is two-fold, thanks to the lower insertion loss and higher input power handling capability compared to earlier models. To support the 3065A a new version of Aeroflex's PXI Studio application software v1.11 is also available.
