APPLICATION NOTE REPLACEMENT PART REFERENCE GUIDE: AN‐60‐060 ORIGINAL PART: REPLACEMENT PARTa,b: MAR‐8SM+, MSA‐0886 (Avagotech) MAR‐8ASM+ This replacement part has been judged by Mini‐Circuits Engineering as a suitable replacement parta,b APPLICATION CIRCUITS ORIGINAL PART: MAR‐8SM+ & MSA‐0886 (Avagotech) REPLACEMENT PART: MAR‐8ASM+ CONCLUSION: 1)
2)
3)
FORM‐FIT COMPATIBLE: Same Circuit and PCB Layout, change in Bias Resistor Value per table above If Rbias>250 ohms, RFC can be eliminated. 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: Performance Gain (dB) Noise Figure (dB) Pout 1dB (dBm) Output IP3 (dBm Input Return Loss (db) Output Return Loss (dB) Operating Voltage (V) Operating Current (mA) Status Condition(GHz) 1.0 1.0 1.0 1.0 DC‐1 DC‐1 ‐‐‐ ‐‐‐ ‐‐‐ MAR‐8SM+/MSA‐0886 22.5 3.3 12.5 27.0 See Page 2 See Page 2 See table above 36 Qualified, last time buy MAR‐8ASM+ 25 3.1 12.5 25 15.5 11.0 See table above 36 Qualified, in production 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‐0886 part number is used for identification and comparison purposes only. Rev: Draft 1 Page: 1 of 2 APPLICATION NOTE REPLACEMENT PART REFERENCE GUIDE: AN‐60‐060 COMPARISON PERFORMANCE CURVES: P1dB vs. FREQUENCY
