This antenna is connected to the transmission (Tx) patch antenna by means of a frequency doubler
. The Tx antenna is loaded with an interdigital capacitor with a capacitance dependent on the humidity so that, when the relative humidity changes, the antenna is detuned.
The new CVC055CXT-5685-5780 Coaxial Resonator Oscillator (CRO) from Crystek (Fort Myers, FL) is a coaxial-based VCO with an internal proprietary frequency doubler
. Features include:
State-of-the-art performance has been achieved by balanced frequency doubler
with Erickson's scheme [1,3], in which the diodes are in anti-series connection with the end of each arm bonded to the metal channel.
6(a) is a simple frequency doubler
if [[omega].sub.1] = [[omega]sub.2] = [[omega].sub.0].
An optional frequency doubler
extends the frequency range to 8.10 GHz.
Craciunoiu, "Nonlinear composite right/left-handed transmission line for frequency doubler
and short pulse generation," Proc.
The design and analysis of a novel balanced-like high conversion gain frequency doubler
is presented, employing alternate power dividing and combining techniques.
Equipped with the optional frequency doubler
module, the Eclipse delivers an output power of up to 1.5 W at 524 nm.
Using Agfa 8E56 emulsions and their favored plate size (which has a surface of approximately 50 sq cm), the system requires 1Joule of light energy at 532nm to make exposures, using two Neodymium amplifiers and a KD*P frequency doubler
The Chameleon Discovery now includes an expanded tuning range, which when coupled with a frequency doubler
, ensures gap-free wavelength coverage from 330nm to 1,320 nm.
