Product Overview
HTH8G07P400H is Watech pulse‑type LDMOS MMIC power amplifier for 1.8 MHz‑700 MHz. It delivers 400W saturated output power at 48V nominal drain voltage, supports CW and pulse operation. ACC2110S‑4L flanged package provides superior thermal performance for ISM‑band, MRI medical, industrial heating, radar and plasma generator systems.
Core Advantages
High Power & Wide Gain Range
400W saturated output power with 21.01‑27.71dB gain across full bandwidth, reduces drive power requirements for amplifier design.
High Power‑Added Efficiency
PAE 56.57%‑64.77% lowers power consumption and thermal stress. Flanged ceramic‑metal package guarantees reliable heat dissipation for long‑run operation.
CW & Pulse Dual‑Mode Support
Compatible for continuous‑wave and pulse applications, 100μs typical test pulse width. Negative temperature coefficient enhances thermal stability under heavy loads.
50Ω System Matching
Standard 50Ω impedance simplifies input‑output matching circuit for industrial and radar projects.

Frequently Asked Questions
Q1: What is the frequency range of HTH8G07P400H?
A: 1.8 MHz‑700 MHz, designed for high‑power pulse and CW RF amplification.
Q2: What is the difference between HTH8G07P400H and HTH8G07P400HB?
A: Different flange package: H uses ACC2110S‑4L, HB uses ACC2110B‑4L. Electrical parameters are close, but not drop‑in compatible. Check PCB mounting dimension before replacement.
Q3: Can this device work in CW continuous‑wave mode?
A: Yes, CW and pulse are both supported. For CW operation, power derating and enhanced heat dissipation are required to avoid over‑temperature damage.
Q4: Are there cross‑brand alternative parts?
A: Select replacements with 48V rating, 1.8‑700 MHz bandwidth and ~400W output. Cross‑brand parts differ in gain and internal matching; direct swap is not possible, matching circuit needs re‑tuning.
Q5: Can I use 50V supply instead of rated 48V?
A: Not recommended. Over‑voltage increases breakdown risk and shortens service life. Keep drain voltage at nominal 48V for stable long‑term operation.
Q6: What does 100μs typical pulse‑width mean?
A: 100 μs is standard test condition. Wider pulse will raise junction temperature, output power must be derated accordingly.
Q7: What should I note for ACC2110S‑4L installation?
A: Ensure good thermal contact between flange and heatsink. Use proper thermal grease and correct screw torque. Poor cooling will cause power degradation.
Q8: How does it compare with overseas‑brand 400W LDMOS?
A: Watech delivers competitive PAE for industrial pulse applications. Overseas counterparts may provide better linearity but cost higher. Pin‑to‑pin compatibility is not guaranteed.
