Frequency Multipliers for Radio Amateurs
First approach is to generate the high frequency directly, at the fundamental, using an oscillatortuned on the desired frequency. Few sensitive issues appears here due to high working frequency as, stability, jitter, phase noise, pulling, pushing, low output power, and cost of the active component to meet the performances

Array Antennas
An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. The individual antennas (called elements) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship. The radio waves radiated by each individual antenna combine and superpose, adding together (interfering constructively) to enhance the power radiated in desired directions, and cancelling (interfering destructively) to reduce the power radiated in other directions. Similarly, when used for receiving, the separate radio frequency currents from the individual antennas combine in the receiver with the correct phase relationship to enhance signals received from the desired directions and cancel signals from undesired directions. More sophisticated array antennas may have multiple transmitter or receiver modules, each connected to a separate antenna element or group of elements.

Vector Finders with InternalAttenuators
VF-145 LA AND VF-145 LMA
The VF-145 LA and LMA models are functionally the same as the VF-145 L and LM on both electrical performance and mechanical specifications. However, the LA and LMA models include an internal PIN diode attenuator that provides up to 12 dB of attenuation (measured at 150 MHz, attenuation decrease slightly as operating frequency increases) to the incoming radio signal. This attenuation occurs after the signal is received by the unit and phase shifted for processing, but before it is placed on the coax feedline to the receiver. In addition, the PIN diode utilized will absorb short burst of RF should transceivers be keyed accidentally by the user. This feature aids in very strong signal DF operations but will not totally guarantee against system overload under very strong RF emissions.

Bulk Current Monitoring Probe
MP-50
The Current Monitoring probes may be used whenever RF current measurements are required. Current measurements are made by placing a current carrying conductor within the “sensing” window of the probe and measuring the probe’s output voltage with an RF detector. Calibration of the probe permits the conversion of the voltages measured to current. Current measurements can be made over the frequency range shown in the transfer impedance curve furnished with each probe. There is virtually no loading of the circuit and the technique permits normal operation of the device under test during measurements. The MP-50 can be used for the procedure for clamp injection when the common- mode impedance requirements cannot be met given in chapter 7.4 of IEC/EN 61000-4-6 „Immunity to conducted disturbances, induced by radio frequency fields”. The MP-50 can also be used as current monitor for BCI testing as per ISO11452-4, RTCA/DO-160 section 20, MIL-STD-461 and various automotive standards.
