Overview
Ic7000 drive is an open-source printed circuit board by sgub, from the sgub/ic7k-driver-pcb repository on GitHub, published under the CC-BY-4.0 licence. It is a 2-layer board of 40 × 19.5 mm with 10 parts on 5 nets, routed with 17 tracks and 21 vias.
It is built around the PD55015-E. Its parts include 5 connectors, 2 capacitors, 2 resistors and 1 transistor.
Main components
1README
README.mdImproved IC-7000 HF/VHF/UHF Transceiver driver stage PCB
Features:
- Reduce pinheader spacing from 1.5mm to 1.27mm, for better availability of parts and easier mating with the PA board.
- Added resistor R103 in series with the gate of the MOSFET, to suppress self oscillication on certain conditions which could burn-off the driver module.
BOM:
- Q504: ST Microelectronics PD55015-E 550MHz/15W MOSFET, PowerSO-10 Package, formed lead.
- R103: Choose a value by experiment from 1ohm (moderate damping) to 10ohm (~50% reduced final output power on UHF, but much safer), size 0805
- R102: 100ohm/1W, Axial_DIN0309_L9.0mm_D3.2mm_P15.24mm. Size is critical due to limited installation space.
- J107,J104,J103,J102,J101: PinHeader_1x04_P1.27mm_Vertical, 11mm total height.
- C102: 39pF/100V, Size 1206.
- C101: 10nF/50V, size 0805.
Build notes:
- Prefered board material is FR4 double layer, 1.6mm thick.
- Apply enough solder between the underside of the MOSFET and the heatsink for effective heat conducting, avoid space, soldering/heating with proper tool. Refer STMicroelectronics AN1294 Application note for temperature limit and technique recommendation.

Questions
How big is the Ic7000 drive PCB?
It measures 40 × 19.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ic7000 drive use?
10 parts, built around the PD55015-E. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ic7000 drive KiCad files?
From the sgub/ic7k-driver-pcb repository on GitHub, at the commit this page was made from: the board is ic7000_drive.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ic7000 drive design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
