Product Overview
The RQA0009SXAQSTL‑E is Renesas N‑channel RF power MOSFET for 400‑900 MHz VHF/UHF amplifiers. It delivers 6W output power @520 MHz with high PAE, optimized for low‑voltage battery‑powered equipment. Packaged in compact SC‑62 (SOT‑89 variant) SMD housing with built‑in diode, it features good gain and strong load‑mismatch ruggedness for land mobile radios and wireless transmitter modules.
Core Advantages
High RF Performance
18 dB typical gain, up to 65% PAE at 520 MHz, lowers power consumption and thermal stress for VHF/UHF amplifier designs.
Low‑Voltage Battery Operation
Supplies 1.5‑7.5 V, recommended 4.8‑6 V, ideal for handheld portable radios and battery‑driven RF modules.
Compact SMD Package
SC‑62 (SOT‑89 variant) 3‑pin package with internal diode, saves PCB space for SMT radio layouts.
Excellent Ruggedness
High VSWR withstand capability, protects power stage against antenna mismatch and load fault conditions.

Frequently Asked Questions
Q1: What does suffix “STL‑E” mean in RQA0009SXAQSTL‑E?
A: “STL” means tape‑and‑reel for automatic SMT assembly. “-E” stands for RoHS lead‑free. It shares identical electrical specs with RQA0009SXAQS / RQA0009SXTL‑E series.
Q2: What is the physical package for this RF MOSFET?
A: SC‑62 (SOT‑89 variant), 3‑pin SMD package with integrated protection diode.
Q3: What frequency and power level can this device achieve?
A: Typical 6 W output at 465‑520 MHz; usable up to 900 MHz with power derating. Recommended supply: 4.8‑6 V.
Q4: Can I use other brand RF MOSFET as cross‑brand replacement?
A: Cross‑brand substitution is not drop‑in. Match Vdss, frequency, power rating, package and impedance. Circuit re‑tuning is mandatory even for similar‑spec parts.
Q5: Are there pin‑to‑pin compatible alternative part numbers?
A: Check other Renesas SC‑62‑packaged RF MOSFETs. No fully drop‑in public replacement. Compare Id, Vdss, gain and PAE before PCB revision.
Q6: What are key design notes when using RQA0009SXAQSTL‑E?
A: This is RF‑only transistor, not for general‑purpose switching. Implement proper impedance matching, Idq biasing and thermal design for stable amplifier performance.
Q7: How can I get datasheet and volume quotation?
A: Submit your request via Quick Inquiry form. We provide original datasheet, stock confirmation and bulk price within 24 hours.
