RF / High-Frequency PCB
An RF and high-frequency PCB manufacturer running Rogers, PTFE and mixed-dielectric constructions — controlled impedance, low loss, and hybrid stackups for microwave and mmWave designs.
Key Capabilities
RF performance lives in the material and the impedance. As an RF and high-frequency PCB manufacturer, we run Rogers, PTFE and Panasonic laminates — and the harder hybrid builds: Rogers 4350B/4003 bonded with FR-4, and pure-Rogers multilayers. We hold controlled impedance to ±8% (±5 Ω at ≤50 Ω) and minimum 2.5/2.5 mil line and space, with RF-friendly finishes like immersion silver and ENIG. Mixed-dielectric stackups let you put the RF layer exactly where it's needed without paying for an all-PTFE board. Built for low-volume, fast-turn microwave and high-frequency prototypes, to IPC Class 3.

Engineering Highlights
- Rogers, PTFE & hybrid stackups
Match material to RF performance.
- Mixed-dielectric construction
RF layer where you need it, FR-4 elsewhere.
- Controlled impedance to ±8%
For predictable RF behavior.
- RF-grade finishes
Immersion silver / ENIG for low insertion loss.
Why it's hard
Mixed-material lamination, bond reliability between dissimilar dielectrics, and impedance held across the RF stack.
How we build it
Validated Rogers/PTFE/hybrid processing in-house with controlled-impedance routing and RF finishes, to IPC Class 3.
Applications
5G base stations, remote radio units and mmWave modules; automotive radar (24 GHz / 77 GHz) and ADAS; satellite / SATCOM and antenna feed networks; RF amplifiers, filters, couplers and power dividers; aerospace/defense RF and EW; test & measurement.
Material Selection
Choosing the laminate is the first RF decision. As an industry guide (we confirm exact material and availability with your design):
PTFE / ceramic — lowest loss, for microwave/mmWave:
- Rogers RO4350B — Dk 3.48, Df ~0.0031–0.0037 @10 GHz — the workhorse for 5G macro, modules, couplers.
- Rogers RO4003C — Dk 3.38, Df ~0.0027 @10 GHz — lower loss; high-frequency and RF+high-speed hybrids.
- Rogers RO3003 — Dk 3.0, Df ~0.0013 — mmWave / automotive radar, 50 GHz+.
- Rogers RT/duroid 5880 — Dk 2.2, Df ~0.0009 — 60 GHz+ mmWave, satcom.
- AGC Taconic TLX-8/9, TSM-DS3, TLY-5Z — PTFE/ceramic-filled equivalents.
Hydrocarbon — mid/high-end value, standard-process friendly:
- Isola I-Tera MT40 (Dk ~3.4), Panasonic R-F700, TUC TU872SLK, ITEQ IT-988G, Shengyi S6G — 5G indoor, Wi-Fi 6/7, BLE, IoT RF modules.
Modified low-loss FR-4 — low-frequency RF (<6 GHz):
- Isola FR408HR, Shengyi S1000-2M — BLE, 2.4 G Wi-Fi, RFID.
RF metal-base — RF power amplifiers / high power:
- PTFE-on-aluminum (Rogers/Taconic) for high-power high-frequency.
Pairing rule: PTFE boards use PTFE prepreg, hydrocarbon uses hydrocarbon PP — never mix with ordinary FR-4 PP. Use low-profile (LP) copper to cut RF insertion loss.
Design & DFM
- Reference every controlled-impedance trace to a solid plane; never route RF over a plane split.
- Account for copper roughness — LP/VLP copper reduces insertion loss at high frequency.
- Plan the hybrid stack early: dielectric placement, bond plies and symmetry drive impedance and warpage.
- Choose finish for loss — immersion silver / ENIG.
- Send target impedances and frequencies; we tune lines and confirm with coupons.
Proven
Controlled-impedance RF builds verified with coupons to ±8%.
Beyond the datasheet
For unusual material combinations, extreme frequencies, or stackups past standard windows, our engineers evaluate, prototype and co-develop a manufacturable solution with your RF team.
RF Laminate Loss Comparison
Loss tangent (Df) at 10 GHz — lower is better. FR-4 shown as a high-loss baseline.
Controlled Impedance
Impedance is set by dielectric constant, dielectric height and trace geometry; we tune line widths to your target and hold ±8%.
Evidence
Controlled-impedance, mixed-dielectric builds verified with coupons and TDR to ±8%, to IPC Class 3. Cross-sections show the Rogers-to-FR-4 interface and plated vias these boards depend on.
