Product Overview
The PH1214‑110M is silicon NPN RF power BJT for L‑band pulsed radar (1.2‑1.4 GHz). Under official 150 µs pulse width, 10% duty‑cycle test condition, it delivers 110W peak pulsed output power with high gain and collector efficiency. Gold metallization and emitter ballasting structure improve device reliability. Hermetic flange‑mount package is suitable for ATC, military and marine radar transmitter systems.
Core Advantages
High Peak Power for L‑Band Radar
110W peak pulsed power covering full 1.2‑1.4 GHz L‑band for radar transmit amplifier stages.
Gold Metallization & Emitter Ballasting
Built‑in emitter ballasting prevents thermal runaway, improves current uniformity and long‑term reliability under pulse working conditions.
Integrated Input‑Output Pre‑Matching
Internal impedance pre‑matching reduces external circuit tuning work and keeps consistent performance among devices.
Hermetic Flange Chassis‑Mount Package
Metal‑ceramic hermetic flange package for chassis mounting, excellent heat dissipation for pulsed high‑power operation.

Frequently Asked Questions
Q1: What is main application and power rating for PH1214‑110M?
A: It is an L‑band pulsed radar transistor for 1.2‑1.4 GHz, delivering 110W peak pulsed RF power under official 150µs, 10% duty‑cycle test condition.
Q2: Is external impedance matching required for PH1214‑110M?
A: Internal pre‑matching is integrated, simplifying PCB design and stabilizing RF performance across 1.2‑1.4 GHz frequency band.
Q3: What are official test pulse conditions?
A: 150 µs pulse width, 10% duty‑cycle, 40V collector supply. Continuous‑wave operation without pulse modulation is forbidden.
Q4: What pin‑to‑pin compatible alternatives are available?
A: PH1214 series share same footprint: PH1214‑80M (80W), PH1214‑110M (110W), PH1214‑140M (140W). Higher‑power models can substitute lower‑power ones for safety margin; reverse substitution is not allowed for high‑power radar.
Q5: What does suffix “M” mean in PH1214‑110M?
A: “M” represents metal‑ceramic hermetic flange package, military‑grade sealing for harsh radar environment. This series has no plastic non‑M version.
Q6: Can PH1214‑110M run under CW continuous‑wave mode?
A: Not recommended. It is designed for pulsed‑only radar operation. CW operation will cause over‑heating and permanent device damage.
Q7: How to get datasheet, S‑parameter data or bulk price?
A: Please submit Quick Inquiry for datasheets, S‑parameter files, CAD models, stock status and volume quotation.
