	HP 10515A / Agilent 10515A Series 004 Frequency Doubler Input 0.5 to 500 MHz 180 MW max, Output 1.0 MHz to 1.0 GHz $ 225.00 US Please visit: www.torontosurplus.com for further details. This Frequency Doubler is an ideal accessory for use in extending the usable frequency range of signal generators, frequency synthesizers or other signal sources. This 50 ohm device uses a full-wave rectifier circuit which is extremely flat over its entire frequency range. the frequency response is very flat (< + 1 dB over entire range typically), and undesired harmonics are very well suppressed. The output of this unit does not have an internal dc return, so that it will provide a very boadband ac to dc conversion only if not dc terminated. This mode of operation is useful for detection of low level amplitude modulations. Connectors: Input - BNC Male, Output - BNC Female. 1 in stock $ 225.00 US
