10GHZ input - Down Converter 3LNC70 - 432MHz output

 

10 GHz input      and    70cm band Output  , with option ext. GPS input

It is my pleasure to present a new product for 10GHZ amateur radio operators from www.hides.com.tw
Low-noise selective 10GHZ LNC in coaxial form
( for various applications… direct 10GHz FM-SSB QSO , DVB-T QSO , QO100 SSB QSO , QO-100 DVBt or DVBs QSO )
and power supply either via coax or external.

Size: 70 x 47 x 21mm
Input-Output-Ext LO connectors: 50ohm , SMA female
Noise figure: 1,2~1,3dB
Recommended RF input range: 9,8GHz.......10,7GHz
Recommended IF output range: 300.........2000 MHz
Recommended Vcc voltage: 8V.....14V
Recommended Freq. range for Ext. LOsync input: 25,4......29,8MHz ( with the internal quartz switched off )

LNC consumption in original condition is approx. 150mA , power supply options here......

Technicians who want to install a TCXO with more stability themselves, there is enough space on the underside of the PCB.
HiDes provides the 3.3V power supply on the PCB point TP1 and TP2 with max. 100mA

Various uses that are feasible, such as....

3LNC70 Conversion gain: 28~29dB

Due to the use of first-class PCB substrate and many plated-through holes,
absolutely no tendency to selfoscillate was determined , whether with or without housing !!.


3LNC70 use with original quartz built in......

....according to the data sheet, built-in quartz has a TC of 8ppm in the range from -20°C to +60°C


and using an external clock signal via Ext. port connector....

.....and a few other stabilization options, but only suitable for technicians:

Example in use with QO-100 SSB signals and 3LNC70 in original condition:
10.489500~10.490000GHz - 10.0575GHz = 432,000~432,500MHz

Version for Amateur Television :        3LNC70 ATV

3LNC ATV
What is different from 3LNC70 for SSB mode ?
Other quartz for other local oscillator frequency and output attenuator removed ( DVB-S receiver needs higher input level ).

And what amplification does this model have ?

Example in use with QO-100 ATV signals     and      3LNCatv in original condition:
10,491~10,499GHz
- 9,540GHz
================
951,000~959,000MHz
