Advantages
Ultra-low Noise Figure
The use of low-noise gallium arsenide/silicon germanium process and precise matching network significantly reduces the noise figure.
Wideband Operating Range
Wideband input/output matching structure enables coverage of a wider RF band, reducing the number of devices customers need in multi-band applications.
Gain Stability
Gain and noise remain stable over a wide temperature range through temperature compensation and linear bias control.
Packaging and Shipping
Products are protected with anti-static bags, desiccants, and shock-absorbing foam; bulk orders use Tape & Reel or Tray packaging, conforming to JEDEC/IPC standards.
We support global air and sea freight pallet shipping via DHL/UPS/FedEx to ensure safe delivery of components.

FAQ
Q: What are your LNA linearity and noise performance specifications?
A: Yes, we can provide complete test reports including OIP3, NF, and Gain, and support customized data by frequency band.
Q: Can you customize the frequency band or gain?
A: Yes. We support OEM/ODM services such as network matching, gain customization, and package customization.
Q: What is your MOQ and pricing structure?
A: Standard MOQ is 500–1000 pcs; tiered pricing is available for large orders.
Q: Do you have commonly used models in stock? What is the lead time?
A: Mainstream frequency band models are always in stock and can be shipped on the same day; customized models have a lead time of 2–4 weeks.
Q: What is your quality control process?
A: Each batch undergoes 100% functional testing (Gain, NF, OIP3, S11, stability). High and low temperature cycling and aging screening are also performed.
Q: Do you provide technical support?
A: We provide full-process support including LNA matching, front-end link budgeting, stability analysis, and application debugging.
Q: What about long-term supply capabilities?
A: Core models are guaranteed for 5-10 years of long-term supply, with material backup plans to avoid the risk of production stoppages.
