KXS-2315FM Transmitter

FCC ID: KXS-2315 Circuit Description The 88.1, 88.3, 88.5, 107.1, 107.3, 107.5MHz are generated by U1 to drive the base of Q2 the final/buffer amplifier. The modulation provided by the 3.5mm stereo jack J1 input. The output of Q2 has the matching network consisting of L4 and C19, C20 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source There is no external antenna. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 12Volt. (Car battery) or a 3Volt (“AAA” size battery x2) primary battery.

Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X,Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, rotating turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. *.

For effective averaging, the bandwidth of the video filter must be smaller than the resolution bandwidth. The higher the ratio of resolution bandwidth to video bandwidth, the greater the averaging will be. Below setting for ESVP, HP8568B, HP85662A and HP85650A EMI Receiver.
