 Hides 2025 microwave news - New products for the:  

1.2    2.4    3.5    5.6    10   and  24 GHz bands 

 

♠♠♠♠♠♠   Multiband  FM TV  Transmitter   ♠♠♠♠♠♠

Project under development  ( hopefully completed by the end of 2026 )

Target features:

■  7 amateur radio bands from 900 MHz to 24 GHz , PLL locked.

■  Output RF power between 10 mW and 60 mW depending on the band.

■  Signal bandwidth compatible with IC-905 receiver   BW 15MHz.

■  For NTSC and PAL modes.

■  Call sign display option selectable.

■  HDMI or CVBS input selectable.

■  Video polarity selectable  ( positive or negative )

■  Two audio carriers ( switchable )   Mono !

■  Simultaneous transmission on any number of bands - possible !!

■  Separate potential-free contact  ( 500mA )  for PA control for each band

■  Operating voltage: 10–14 V

■  Fully calibrated modular technology for self-installation in an enclosure, consisting of two modules: Control and TX board.

The control unit hardware is already finished , the first hardware prototype is complete. 

Schematic, software and PCB Layout by DL1MFK.

Max. RF input power :     20mW          (  You'll break it with 250mW   )

Bandwidth:   very wide , from under 9GHz to over 13GHz. ( if your pilot signal is not clean, then you need a bandpass filter before the amplifier !  )

Operating voltage :    8.....15 Volt       Typ. 12V     Electricity consumption :    max.  1 Amper

Optional Vcc :      5.8V    (  max. 6.1V )    Consumption:  max. 2A

The inner workings of an amplifier......

During the PCB design, a great deal of attention was paid to good RF performance transmission :    
such as good RF substrate ROGERS material , good ground connections between top and bottom layer , 

hundreds of vias - almost invisible to the naked eye , good low-loss connection to the SMA connector , 

good rapid heat dissipation ,  etc.

about:   382euro

The operating voltage is 8V to 15V , but the module can also be operated with 6V  ( tolerance range 5,9V.....6,0V )

What needs to be done then ?   ....For technicians only !!

Optional:    operating voltage  6V

1.     remove R2

2.     connect....

The same applies to multipliers with power amplifiers !!!

♠♠♠♠♠♠ Multiplier  with  10GHz  Power Amplifier ♠♠♠♠♠♠

This is 98% the same design and circuit diagram , only one additional Hittite multiplier IC has been added.

The inner workings.....

There are two versions.....

1.    Input   1200......1320MHz     ( x8 )        -20dBm ..... 3mW             50ohm

2.    Input   2460.....2630MHz      ( x4 )        -20dBm ..... 3mW             50ohm

No matter what power you give to input ( -20dBm..... +5dBm )  ,   at 10GHz the output is always over 2W 

Output:   9,60 GHz ....... 10,56 GHz        > 2.0 Watt output power in CW mode        & 50ohm

"Conversion gain" :     >50dB

Monitor RF pin:      negative ,      -1.75V  &  2.37 Watt  RF output

Vcc  &  Icc :       8.......15 Volt          1 Amper & 12V        ( optional Vcc:  6V   )

Use purpose: 10GHz signal source, beacon transmitter, CW transmitter, FM transmitter, FMTV transmitter, etc.
