(AD-(9) Tune-up procedure at specific operating power levels:
(1) Vcc vollage of RF AMP block
DC-DC converter output is +5V constant. It supplies Vcc of the RF AMP blocki
Voltage regulator output is +3V constant. It supplies Vcc uftlre VCO(CP401).
(2) Measurement of RF power output.
RF power output is measured at output terminal (CNAOZ).
VCO(CP401) output is applied to RF AMP block and the output is applied to L.P.F.and
isolator. So RF power output is decided by VCO and RF AMP block output power,
LP.F. insertion loss and isolator insertion loss,
1) VCO RF output power is —1.5 ~ +2.0dBm(at 509 load) at 3V power supply voltage.
2) Adjust Cl'401 and RV401 so that RF AMP block output power is 16 ~ 19dBm (at 509 load)
when RF AMP block input power is -1.5 - +2,0dBm and SV power supply
voltage.
3) L.P.F. insertion loss is less than 0.6dB,
4) isolator insertion loss is 0.5 — 0.9dB.
Therefore RF output power is 50mW(15m‘¢V) by adjusting CT401 and RV40L

frequency:
Determination and stability of frequency on PLL synthesizer
1. Divide the oscillation frequencym from the VCO(CP401) by a presczler[1/M](IC401).
A wunter[1/A](IC401) and N counter[1/N](IC401) and apply it [fr'] to a phase detectort
fr’ = f (1)
MNsA
2. The integrated output signal of the phase detedor, which is taken by the phase difference from[£r’] to a reference
oscillatorlfi], and use the signal as the control
voltage for the VCO.
3. With the above 1 and 2(Ioop 1 through 2), the circuit maintains its balance
fr = fr' ---- (2)
by expression of (1), (2)
f = (MN+A)fi ---- (3)
4. Therefnre transmitting fi'equencym is determined by [M], [N], [A], [fr] and stability is decided by stabilityvf
reference frequencyfi'r}
5. Stability of the reference frequencflfx] is 135ppm(by stability of X‘I|I(X551) spec).
So stability of tran smitling frequeney[f| is tSOppm(04005%).

(d)—(11)A description of clrcuits for suppression of spurious radiation:
1. Radiation of higher harmonics are suppressed by installation of low pass filter
and isolator in the next to a RF mil
2. By intruducing direct oscillalion system of lransmilting frequency by the VCO, RF
AMP are straightly amplified. So there is no spurious caused by frequency
multiplier.
3. Shield of the VCO and the RF AMP block suppress spurious emission radiated from the transmiller chassis.

A. Measurement procedure
1. The measurement shall be made on an open field test site which is free from reflecting objects that may afl'ect the
measurement results.
2. For radiated power output of the equipment, the measuring antenna was raised and lowered to obtain a maximum
reading on the spectrum analyzer with the antenna vertically and horizontally polarized. The turntable was
rotated a minimum of 360” to further increase the reading on the spectrum analyzer. Then field strength was
recorded in dB at V/m.
3. The unit was removed and replaced with a dipole antenna. (The antenna was adjusted to a half-wave of
transmitting frequency.) The center of the dipole antenna was placed approximately at the same location as the
center of the unit.
4. The dipole antenna at the unit end was connected to a signal generator with a coaxial cable. Wilh the antennas at
both ends vertically and horizontally polarized and signal generator tuned to the transmitting frequency, the level of
the signal generator output was adjusted to the previously recorded maximum reading for this set of conditions was
obtained
5. The input power into the dipole antenna was calculated from the coaxial cable loss and the signal generator output
voltage obtained in these readings.

A—l. Measurement procedure (from lowest frequency to lOOOMHz)
1. The measurement shall be made on an open field test site which is free from reflecting objects that may afleot the
measurement results.
2. This procedure was intended to determine the level of spurious emission radiated from the antenna and the unit
chassis. The radio frequency spectrum was scanned from lowest frequency generated in the equipment to
IOOOMHZ.
34 For each spurious or harmonic measurement, the measuring antenna was adjusted to the correct length for the
frequency involved. This length was made from the lowest frequency generated in the equipment to IOOOMHZ.
4. For each frequency generated in the equipment, the measuring antenna was raised and lowered to obtain a
maximum reading on the spectrum analyzer with the antenna vertically polarized The turntable was rotated a
minimum of 360' to further increase the reading on the spectmm analyzer. Then field strength was recorded
in dB“ Wu).
5. The unit was removed and replaced with a dipole antenna. (The antenna was adjusted to a half-wave of
transmitting frequency.) The center ofthe dipole antenna was placed approximately at the same location as the
center of the unit.
6. The dipole antenna at the unit end was fed with a signal generator. With the antennas at both ends vertically
polarized and signal generator tuned to the transmitting frequency, the level of the signal generator output was
adjusted to the previously recorded maximum reading for this set of conditions was obtained.
7. The entire procedure for each spurious and harmonics frequency with the FSM antenna horizontally polarized was
repeated.
8. The input power into the dipole antenna was calculated from the impedance and the sign] generator voltage
obtained in these readings.

measurement results.
2. This procedure was intended to determine the level of spurious emission radiated from the antenna and the unit
chassis The radio frequency spectmm ms scanned from IGHz frequency generated in the equipment to IOGHz.
3. For each spurious or harmonic measurement. the measuring antenna was changed according to frequency range.
4. For each frequency generated in the equipment, the measuring antenna was raised and lowered to obtain a
maximum reading on the spectrum analyzer with the antenna vertically polarized. The turntable was rotated a
minimum of 360' to further increase the reading on the spectrum analyzer. Then field strength was recorded in
