Double

The purchase of a call and a put on the same underlying asset with the same strike price and the same expiration date. A double enables one to profit from whatever price movement the underlying takes. That is, if the price goes up, the holder exercises the call, and if it goes down, he/she exercises the put. If one of the options is in the money, the other must be out of the money.

The circuit is known as voltage doubler since output voltage is double than the input voltage.

You can't have a nursing home doubler without buying an annuity, of course, and even a modest annuity is not inexpensive.
The design and analysis of a novel balanced-like high conversion gain frequency doubler is presented, employing alternate power dividing and combining techniques.
A second balanced doubler is used as the output stage for the 50 to 75 GHz Source Module and the output interface is WR-15 waveguide.
Conversion loss for the doublers is typically 15 dB at a drive level of +15 dBm.
With the scarcity of available sweepers and insufficient output power to energize the mixers, an optional frequency doubler was sought that allowed local oscillator operation at half of the 26 to 40 GHz LO frequency.
Although the frequency doublers exhibited acceptable performance for this application, the DC bias and input power operating points were found to be somewhat critical to optimum performance.
The best operation for frequency doublers is with a load resistance from 5 to 10 [omega] where circuit efficiency will be high and both power output and bandwidth will be of sufficient magnitude.
