Product Overview
The BLF184XR is an extremely rugged 650 W pulsed LDMOS power transistor from Ampleon (formerly NXP Semiconductors) for broadcast and ISM applications, covering HF‑600 MHz. The XR family supports VSWR＞65:1 all‑phase load mismatch without damage. Built‑in ESD protection, high efficiency and good thermal stability. Housed in SOT1214A flanged ceramic package, suitable for FM transmitters, laser drivers, plasma generators and MRI RF amplifiers.
Core Advantages
eXtremely Rugged (XR) Architecture
Withstands VSWR＞65:1 full‑phase load mismatch under full power, reduces requirement for external isolators.
High Output Power & Thermal Efficiency
650 W pulsed output power, typical drain efficiency 60%‑73%, lowers system cooling burden.
Wide Frequency Band Coverage
Broadband performance HF‑600 MHz, flexible for multiple industrial RF platform designs.
Integrated ESD Protection & Robust Package
Internal ESD protection; flange‑mount ceramic package for direct heatsink installation for reliable heat dissipation.

Frequently Asked Questions
Q1：What does “XR” mean for BLF184XR?
A：XR = Extremely Rugged. The transistor withstands VSWR＞65:1 all‑phase load mismatch under full pulsed power without damage.
Q2：What is the actual output power of BLF184XR?
A：Datasheet spec: 650W Pulsed @108MHz, 50V Vds. Some distributors show 700W which is platform entry error. This device is not 700W CW; continuous‑wave operation needs thermal de‑rating.
Q3：Difference between BLF184XR, BLF184XRS, BLF184XRGQ, BLF184XRGJ?
A：Chip die & electrical parameters are identical, only mechanical package differs:
- BLF184XR / BLF184XRGQ：SOT1214A, flange with 2 mounting holes, tray bulk pack, mutually interchangeable.
- BLF184XRS / BLF184XRGJ：SOT1214B, hole‑free flange, tape‑reel. Cannot reuse existing mounting fixture directly.
Q4：Any pin‑to‑pin drop‑in compatible alternatives?
A：No full drop‑in replacement. Within Ampleon XR series you can evaluate BLF183XR (lower power) and BLF188XR (higher power). Both require circuit re‑matching and fixture modification. Competitor LDMOS cannot substitute directly.
Q5：What is the difference between SOT1214A and SOT1214B?
A：Pin assignments are the same. SOT1214A has two mounting‑hole flange for screw fixing（BLF184XR）；SOT1214B is hole‑free flange for tape‑reel assembly（BLF184XRS）. Mechanical mounting dimensions are not compatible.
Q6：How to get datasheet, simulation model or bulk quotation?
A：Submit inquiry form to receive official datasheet, application note, RF simulation model, stock status and volume price.
