Application Circuits

Conclusion:

  1. FORM-FIT COMPATIBLE: Same Circuit and PCB Layout, change in Bias Resistor Value per table above
  2. If Rbias>250 ohms, RFC can be eliminated.
  3. Original part MAR-8SM+/MSA-0886 has poor Input and output return loss, 4 to 14 dB vs. MAR-8ASM+ has 12‐16 dB typically over 50-1000 MHz.  May affect external matching elements.
  4. Typical Performance Comparison a,b:

Comparison Performance Curves:

Notes:
a. Suitability for model replacement within a particular system must be determined by and is solely the responsibility of the customer based on, among other things, electrical performance criteria, stimulus conditions, application, compatibility with other components and environmental conditions and stresses.
b. The MSA-1105 part number is used for identification and comparison purposes only
