Loop antenna Model GA-800 Antenna loop size 260mm/10.2" (inner diameter) Control box 107 x 65 x 26mm/4.2 x 2.6 x 1" Working frequency 10KHz-159MHz Operating Voltage 5V/1A Impedance 50Ohm Gain 20db (Max) Weight 0.65kg Packaging and delivery ...
While this circuit provides a negative resistance and a negative inductance, in series, which appear, looking into the noninverting input of the operational amplifier, in parallel with the antenna, these negative impedances appear in a series loop with the antenna positive impedances, so as to ...

No longer manufacturered new. Possible alternate solution is the Teseq HLA 6121. 9kHz - 30MHz The HLA6120 is ideal for the 3m magnetic field measurements as required by VDE 0871 and FCC 18. The built-in preamplifier matches the extremely low impedance of the loop to the measuring receiver....

Figure7g–j present a variety RFIC functionality measurements. Figure7g shows digital control of the output power through the power amplifier cascode voltage. The phase noise performance of the frequency synthesis chain is shown in Fig.7h. The spectrum is measured through a frequency divider that se...
[Mark] had his eyes on the nice quadrifilar helical antenna used by the Vaisla R92 radiosonde’s GPS receiver, with the aim of repurposing them. He had a lot of components to remove while still retaining the low-noise amplifier (LNA), but in the end managed to get a working antenna ...
Finally, the power amplifier may be a hybrid device using, for example, solid-state technology for the initial low-power stages and VEDs for one or more high-power output stages. Finally, the phase-conjugated RF pilot signal 118 is radiated by the transmitting antenna 120 of the kth array...
