Frequently Asked Questions
Q1: What is difference between HT647PL and HT647PLB?
A: Electrical specifications are identical. HT647PL is reel‑packed, HT647PLB is tray‑packed. No difference in performance or pin‑out.
Q2: Can HT647PL work for CW continuous‑wave operation?
A: Yes, supports CW operation. Proper heatsink cooling is required to keep junction temperature within‑55℃ ~ +175℃.
Q3: Is this device pin‑to‑pin drop‑in replacement for other brand 200W LDMOS?
A: Not direct drop‑in. It is an unmatched transistor. Even if package looks similar, input‑output matching network must be re‑tuned before substitution.
Q4: What does exposed back‑side pad stand for?
A: The back flange pad is Source terminal, not ground. Do not short it to chassis ground directly without design review.
Q5: Are evaluation boards available for HT647PL series?
A: Yes, EVB reference boards: HT647PL(B)EVB and HT647PL(B)EVB1 for circuit prototype testing.
Q6: What is the recommended drain operating voltage?
A: Nominal 28 V DC, operating range 20‑28 V DC. Do not exceed maximum drain voltage rating.
Q7: What frequency range is HT647PL best‑suited for?
A: Optimal performance within 1.8 MHz‑600 MHz. Gain and efficiency will degrade outside this band.
Q8: Does HT647PL tolerate high VSWR load mismatch?
A: Limited mismatch tolerance. External protective circuit is required against high VSWR to avoid device damage.
