Recycle Qorvo Evaluation Board:GaN Driver Amplifier,Phase Shifter,SPDT Switch

Shenzhen Mingjiada Electronics Co., Ltd. is a leading electronic component recycling service provider in China, specialising in the high-price recycling of various electronic component products. With nearly 30 years of industry experience, the company has established a global recycling network and a professional evaluation system to provide customers with efficient, safe, and compliant inventory management solutions.

Recycling Advantages

High-price Recycling: Leveraging a global procurement network and market insights, the company offers the most competitive recycling prices to help customers maximise cash flow.

Quick Cash Conversion: Standardised evaluation processes and sufficient financial support ensure customers complete transactions and receive cash in the shortest possible time.

Compliant Operations: We only recycle components sourced from authorised distributors, traders, and end-user factories, ensuring all transactions are legal and compliant.

Professional Recycling Service Process

Inventory Classification: Customers must classify their surplus products, specifying model numbers, brands, production dates, and quantities.

Submit List: Send a detailed inventory list via fax or email to the company's evaluation team. The list should include product model, quantity, packaging, batch number, and physical condition.

Quotation and Agreement: After evaluation by company professionals, a market-competitive quotation is provided. Upon agreement, the transaction method (cash purchase/consignment/exchange, etc.) is determined.

Sample Testing: Customers may send samples or arrange for on-site sampling and testing to ensure products meet recycling standards.

Delivery and Payment: After confirming the price, a contract is signed. We support on-site pickup or logistics delivery. Upon verification of goods, full payment is made in one lump sum (bank transfer, wire transfer, etc.).

【Gallium Nitride (GaN) Driver Amplifier Evaluation Board】The Cornerstone of High Power and Wideband Performance

Gallium nitride technology has become the preferred choice for driver amplifiers, particularly in satellite communications, radar, and point-to-point radio applications, owing to its high power density, high efficiency, and wide bandwidth characteristics.

QPA2966EVB: This evaluation board assesses the QPA2966, a 20W broadband GaN power amplifier.

Frequency Range: Covers 2 GHz to 18 GHz, demonstrating exceptionally wide bandwidth.

Output Power: Saturated output power reaches up to 43 dBm (approximately 20W).

Process technology: Utilises the QGaN15 GaN-on-SiC (Gallium Nitride on Silicon Carbide) process, ensuring excellent performance and reliability at high power levels.

QPA1009EVB: For evaluating the QPA1009, a 17W broadband GaN power amplifier.

Frequency range: Focused on the Ku-band from 10.7 GHz to 12.7 GHz.

Output power: Delivers 42 dBm saturated output power and 16 dB large-signal gain.

Design Features: Its RF input port is DC-grounded, providing optimised ESD (electrostatic discharge) protection.

【Phase Shifter Evaluation Board】The Key to Beamforming

Phase shifters form the core of phased array antenna systems, precisely controlling the phase of each radiating element to achieve electronic beam scanning. Although no standalone phase shifter evaluation board model is directly listed in search results, Qorvo's highly integrated front-end module (FEM) evaluation boards typically incorporate phase shifter functionality.

QPF4659EVB: An evaluation board for the QPF4659 front-end module. Such integrated front-end modules typically incorporate low-noise amplifiers, power amplifiers, phase shifters, and attenuators.

Operating Band: 5.925 GHz to 7.125 GHz, suitable for applications such as 5G infrastructure.

【Single Pole Double Throw (SPDT) Switch Evaluation Board】 Signal Routing and Protection

SPDT switches are employed for switching between two RF paths, finding extensive application in TDD (Time Division Duplex) systems, radar transmit/receive switching, and test instrumentation. Qorvo offers switch evaluation boards based on various technologies, such as SOI and GaAs.

QPC6324-related evaluation boards: Although search results do not directly specify evaluation board models, the QPC6324 is a typical SOI-based SPDT absorptive switch designed for 4G/5G wireless infrastructure.

Key features: High isolation, excellent linearity, and simplified design with no DC-blocking capacitors required on RF ports.

Logic Compatibility: Compatible with +1.8V logic levels, suitable for modern low-power digital control circuits.

RFSW6024PCK-410: This is an explicit SPDT switch evaluation board operating within the 5 MHz to 6 GHz frequency range.

Type: Absorption switch. In the off state, ports are terminated to a 50-ohm load, effectively reducing signal reflections and enhancing system stability.
