Short description Transmitter HT40:
Audio part:
The dynamic unit (D880) is connected via L1-L2-C6-C7 (RF-filter), to the MICAMP stage.
The MICAMP is built as an amplifier, which is a part of the NE575- integrated circuit and has
a gain of 8.8dB. It also forms the LOCUT
filter at 30 Hz. Then the signal is fed to the
COMPressor.
Here the dynamic of the amplitude is reduced to its half value, expressed in dB. This
compressor is built with the integrated circuit NE575 from Signetics. In the feedback loop of
the amplifier (Pin 12 and 14) there is the variable gain cell inserted. The variable gain cell
is controlled by the rectified output voltage of the amplifier. C60 smoothes the rectified
signal an controls the variable gain cell. C60 defines the so called time constant of the
compressor. This feedback loop leads in an compression of the input signal. R7-R8-C10
build the DC path in the feedback loop.
The second amplifier is used to build the PREEMphasis circuit, which boosts the higher
frequencies with an time constant of 50usec and a fixed gain of 7.9dB at the lower
frequencies.
The DEViation ADjustment is realized with the potentiometer R16. Here at an input level of
100mV/1kHz the deviation is adjusted to 15kHz, which is the nominal modulation. Also at
MUTE-position of the main switch, the signal is here shorted.
Q2 with the additional parts form the HICUT filter at app. 25 kHz/3rd order.
Via C29-R28-C30-R30 the signal modulates the CCO.
RF part:
The UHF Signal is generated by a crystal controlled oscillator CCO and multiplier amplifier
stages (AMP1, AMP2, AMP3, AMP4).
The third harmonic of the CCO is filtered by BPF1, after 3 doubler stages Ftransmit/2 is
filtered by BPF2. After the output amplifier AMP5 the signal is filtered by LPF and a ceramic
filter BPF3.

Short description Transmitter PT40:
Audio part:
The input signal is connected at Pin2 via L13L14C44C72 (RFfilter), to the MICAMP stage
(with Pin1 = ground). The supply voltage of 3.9V for the microphones is connected via R68
at pin 3 of the connector . For microphone application Pin2 and Pin3 has to be shorten in
the connector of the microphone. The MICAMP is built as an amplifier, which is a part of the
NE575 integrated circuit and has a variable gain of 0dB to 21dB. It also forms the LOCUT
filter at 30 Hz and the MIC/LINE switch is situated here, which reduces the input signal by
app. 14dB at line position.
Then the signal is fed to the COMPressor. Here the dynamic of the amplitude is reduced to
its half value, expressed in dB. This compressor is built with the integrated circuit NE575
from Signetics. In the feedback loop of the amplifier (Pin 12 and 14) is the variable gain
cell inserted. The variable gain cell is controlled by the rectified output voltage of the

The elements determining the reception frequency are the band pass filter BPF1 and the
crystal of local mixer oscillator XT1
RFPart:
The front end consists of a ceramic pass band filter BPF1, a bipolar transistor amplifier
AMP1 and a low pass filter LPF. The 1st MIXER1 converts the RF signal to the 1st
intermediate frequency of 56MHz, the 2nd MIXER2 converts the signal to the 2nd
intermediate (demodulation) frequency 10.7MHz.
The 2nd intermediate frequency is band pass filtered (BPF2,3), amplified (AMP2) and gets to
the input of the demodulator IC (LIMAMP and DEMOD).
The 1st mixer oscillator (CCO1) is designed as a crystal controlled oscillator (the 3rd
harmonic is filtered out by BPF4) and multiplier amplifiers AMP3 and AMP4. The LO signal is
filtered by BPF5, BPF6 and is 56MHz below the reception frequency.
The 2nd mixer oscillator (CCO2) is crystal controlled too, his frequency is 45,3MHz.
AudioPart:
The audio signal from DEMODulator (BA4110IFdemodulator) is amplified by AFAMP with
U11Pin123. Here the output signal is adjusted to 500mV/1kHz at 15kHz deviation.
Then the signal runs to the MUTEstage, which is the second half of U11. Muting is realized
with Q29, which shortens the feedback path. Q29 is controlled by the RSSI signal.
The RSSIsignal comes from the IFcircuit BA4110. U7 forms an COMPARATOR, which
switches the MUTEtransistor Q29 at RSSIlevel lower than 98dBm. This value can be
adjusted via SQUELCHpotentiometer VR1.
Q25 builds an HICUTfilter at 20 kHz/2nd order. Amplifier Pin17/18/19 of NE575 forms the
DEEMphasis circuit. The frequencies above 3 kHz are decreased with first order
(timeconstant 50 µsec).
Then the signal is expanded with the EXPander circuit NE575. Here the original level
behavior of the input signal at the transmitter input is restored. The expander time
constant is defined by C48.
The second free amplifier of NE575 is used as buffer before the volume control section.
With VR2 (VOLUME) the output level can be adjusted from line level (500mV) to mic. level
(35mV). The next stage is a amplifier with a gain of 3.9dB OUTAMP.
C39 separates the dcvoltage from the signal and then the signal is fed to the XLR and
6.3mm JACK. Q31 and Q32 build a CLICKSUPPRessioncircuit. In the OFFposition of the
main switch this transistors are turned on. If the receiver is turned ON, the transistors
remain ON for a short time (by C50), so the clicksignals caused by the amplifiers is
suppressed.
The balanced output has symmetrical impedance, which is built by R84/R87 and R88/R89.
The receiver is powered by an external device which is to be connected at the rear panel (DC
jack POWER) and can be turned on and off by a switch at the front panel (ON/OFF). The
internal used voltage (+8V) is stabilized by the DC circuitry (VREG).
