Frequently Asked Questions
Q1: What does “-G” suffix stand for on AH102A‑G?
A: “-G” is Green / RoHS lead‑free version. Electrical performance is identical to standard AH102A.
Q2: Is AH102A‑G still in mass production?
A: Officially discontinued by Qorvo. Only leftover stock is available, no new production runs.
Q3: Why is no external matching circuit needed?
A: 50‑ohm input / output matching is integrated inside chip. Direct connection to 50‑ohm system, saves PCB matching components.
Q4: What comparable cross‑brand gain‑block devices exist?
A: Reference candidates: ADL5606 (Analog Devices), ERA‑55A+ (Mini‑Circuits). Not pin‑to‑pin compatible. Re‑simulation and hardware test are required before replacement.
Q5: Can AH102A‑G directly swap other SOT‑89 RF amplifiers?
A: Direct drop‑in replacement is not recommended. Pinout, bias and internal matching differ even with same package. Verify hardware before use.
Q6: How to handle thermal tab on SOT‑89‑3 package?
A: Solder thermal tab firmly to PCB ground copper for heat dissipation. Add multiple thermal vias for continuous high‑power operation.
Q7: How can I get formal replacement suggestions?
A: Submit your requirements including frequency, output power, supply voltage and package constraints via inquiry form. Our RF engineer will recommend candidate parts.
