The unit consists of two planar diode
detector sections that operate up to +10 dBm RF power levels, a state-of-the-art GaAs FET low noise amplifier (LNA) and two truly DC-coupled MMIC video logging sections in a successive detection arrangement together with internal voltage regulation circuitry.
In addition, the planar diode opens up the possibility of diode circuit integration .
The discontinuities on both sides are not necessarily identical since the planar diode structure is not completely symmetric and the length of the bond wires is not exactly the same on both sides.
The unit employs an integrated multiple planar diode
detector technique with state-of-the-art silicon true DC coupled MMIC video and operational amplifier circuitry to provide up to 80 Mhz of video bandwidth and high speed performance with 45 to 50 dB dynamic range.
The excellent performance of this harmonic receiver is due to the low capacitance and series resistance of these planar diodes
