Power Doubler Module Evaluation Board:

Power amplifier modules are pivotal for enhancing signal chain output capability. Qorvo's recently launched QPA3311 and QPA3316 hybrid power amplifier modules and their evaluation solutions are specifically engineered to meet the stringent demands of next-generation broadband cable networks, such as DOCSIS 4.0.

Both devices utilise Qorvo's proven GaN25 process technology and operate across a frequency range of 45 MHz to 1794 MHz. Their primary value lies in delivering exceptionally high total composite power: the QPA3311 achieves 74 dBmV under 51-carrier conditions, while the QPA3316 surpasses 75 dBmV. This high output power capability enables a reduction in the number of cascaded amplifiers required for network deployments. This simplifies system architecture, lowers infrastructure costs, and effectively improves signal integrity and noise performance across the entire link.

Controlled Attenuator Evaluation Board:

Controllable attenuators are central to dynamically managing system gain, protecting receivers, and enabling automatic level control. Qorvo offers solutions across multiple technologies, from GaAs to SOI (Silicon-on-Insulator), accompanied by ready-to-use evaluation boards.

QPC1008EVB

The QPC1008EVB evaluation board features the QPC1008 chip, which innovatively integrates a 5-bit digital stepped attenuator with a 1dB voltage-controlled attenuator onto a single die. The digital section provides 1, 2, 4, 8, and 16 dB steps, combining with the analogue section to achieve a continuous attenuation range of up to 32 dB. It exhibits low insertion loss of 5.5 dB at 10 GHz, with RF ports internally matched to 50 Ω, significantly simplifying circuit design. This evaluation board serves as an ideal tool for testing precision gain control functions in broadband systems such as point-to-point radios and test equipment.

QPC4614EVB-01

The QPC4614EVB-01 evaluation board offers a dedicated solution for cable television and video distribution networks, which widely adopt the 75Ω impedance standard. Its core chip, the QPC4614, is a 75Ω 6-bit DSA offering a 0.5dB minimum step size and a 31.5dB attenuation range, maintaining high linearity throughout with an insertion loss of just 1.2dB at 1GHz.

Transfer Switch Evaluator Boards:

Transfer Switch govern signal path selection and isolation, with their performance directly impacting system speed, leakage, and power handling capabilities.

QPC1030DEVB

For demanding applications like radar, electronic warfare, and high-power test equipment, the QPC1030DEVB evaluation board demonstrates the robust performance of the QPC1030D SPST (Single Pole Single Throw) switch. This switch covers a wide bandwidth from 2 GHz to 18 GHz and can handle up to 10W of RF power. Its “absorptive” design ensures excellent port matching and isolation in the off state, making it a critical evaluation tool for building highly reliable, high-power microwave systems.

QPC4270PCK

Another noteworthy switch evaluation board is the QPC4270PCK, based on the QPC4270 SPST absorptive switch. Although its frequency and power specifications are not explicitly stated in public documentation, its high isolation, low insertion loss, and fast switching speed make it widely applicable in CATV, set-top boxes, and other general communication systems for signal routing and channel selection. This evaluation board provides developers with a comprehensive platform to validate the switch's performance within specific application environments.
