Low-pass filter

 

3 Tiefpässe
Three low-pass filters for 1.7, 3.2 and 8.0 GHz
In microstrip technology on Teflon substrate.
Transmissonsdämpfung: s21 <0.2-0.4 dB
Attenuation: s21> 50 dB up to 3 - or 5 times the cutoff frequency.
Developed with HP-MDS.

Bias Tee

 

Bias Tee

 

 

Bias Tee 
For trouble-free and wide-band power of the RF line.
Range: 2.5 - 26.5 GHz
Transmission loss: s21 <0.2 - 1 dB
Input reflection: s11 <15 dB

 



Amplifiers

 

Verstärker

 

 

Varying Amplifier 
With SMT components, adaptation and power supply.
For different frequency ranges from 0 to 10 GHz
Varying Reinforcements: s21 40-20 dB

Resonators for Humidity Measurement

 

Resonatoren

 

 

Resonators with small external stray fields, which emit only very small.
This cavity and line resonators have been developed for measuring the moisture.

 



Field Simulations

 

Feldverteilung

 

 

Field simulation of resonator
Field simulation of resonator The resonators for humidity measurement were optimized using HP-HFSS. Through the simulation was the penetration depth in materials with different dielectric properties are determined.
