PMB-2240 Siemens, PMB-2240 Datasheet - Page 27

• Manufacturer Part Number: PMB-2240
• Description: GSM Transmitter
• Manufacturer: Siemens

The S-parameters provided in this section are based on measurements.
Measurement setup for differential in-/outputs:
The input/output impedances are calculated from these parameters.
The impedances are given as equivalent circuit with lumped elements for differential and single ended
in-/outputs.
The high frequency in-/outputs in this section are base inputs or collector outputs.
As equivalent circuit for these in-/outputs a resistor Rp in parallel to a capacitance Cp is derived:
The S-parameters are available on disk.
