It retains the high-precision RF performance of the chip while reducing the operating threshold through convenient design, and is suitable for RF link power regulation needs in industrial communication, instrument testing, medical equipment, and other scenarios.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAdvantages:\u003c\/b\u003e\u003cbr\u003e- Chip level performance: achieve 0.5dB fine stepping, \u0026lt;±0.2dB adjustment accuracy, DC-6GHz broadband coverage, and meet the signal control requirements of professional RF scenarios.\u003cbr\u003e- Convenient operation: physical knob + OLED real-time display, no need for complex numerical control, even beginners can quickly get started; Type-C power interface is compatible with mainstream power devices.\u003cbr\u003e- Industrial grade adaptation: -85 to 150°C wide temperature working range, 0.6W low power consumption, compact size, can be stably integrated into various industrial\/scientific research equipment links.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eApplication:\u003c\/b\u003e\u003cbr\u003e- Industrial communication: signal power regulation for 4G\/5G base stations and microwave radios.\u003cbr\u003e- Instrument testing: link attenuation control of spectrum analyzer and vector network analyzer.\u003cbr\u003e- Medical\/Military: signal link debugging of medical RF equipment and radar systems.\u003cbr\u003e- Research experiments: RF module development, signal link verification, and other scenarios.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eOperation Instruction:\u003c\/b\u003e\u003cbr\u003e- Power supply connection:\u003cbr\u003e1. Interface selection: Use a Type-C data cable to connect the Type-C interface of the module to the power supply (supports DC3.6-15V, recommended 5V\/1A power supply).\u003cbr\u003e2. Power verification: After the power is turned on, the OLED screen lights up and displays the initial attenuation value (default 0dB), indicating that the module is starting normally.\u003cbr\u003e- Attenuation adjustment operation:\u003cbr\u003e1. Adjustment method: Rotate the knob clockwise to increase the attenuation value, and counterclockwise to decrease the attenuation value.\u003cbr\u003e2. Step control: Each rotation corresponds to a 0.5dB step, and the OLED screen displays the current attenuation value in real-time (range 0 - 31.5dB).\u003cbr\u003e3. Adjustment limit: When the knob is turned to the endpoint, there will be a damping sensation, reaching the maximum (31.5dB) or minimum (0dB) attenuation value. Do not forcefully turn it.\u003cbr\u003e- OLED display instructions:\u003cbr\u003e1. The default display screen shows the current attenuation intensity (unit: dB).\u003cbr\u003e2. If there is an abnormal display (such as no number), the power restart module can be unplugged and restarted.\u003cbr\u003e3. The display brightness is a fixed value, suitable for most indoor\/industrial environments.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eReminders:\u003c\/b\u003e\u003cbr\u003e- Input power limit: The input signal power should not exceed 28dBm to avoid module overload damage.\u003cbr\u003e- Impedance matching: Ensure that the input\/output link has a 50 ohm impedance, otherwise it will increase signal reflection and loss.\u003cbr\u003e- Environmental protection: Avoid long-term use in humid and strong electromagnetic interference environments, and additional protection is required in extreme temperature and humidity scenarios.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecification:\u003c\/b\u003e\u003cbr\u003e- Core chip: for ADI HMC624A-EP (0.1-6GHz GaAs digital attenuator)\u003cbr\u003e- Product size: 33 x 50mm PCB\u003cbr\u003e- Attenuation range: 0 - 31.5dB, 0.5dB step adjustment\u003cbr\u003e- Frequency coverage: DC-6GHz (full frequency adaptation of RF signals)\u003cbr\u003e- Step accuracy: ≤±0.2dB (chip level high precision)\u003cbr\u003e- Power supply voltage: DC 3.6 - 15V\u003cbr\u003e- Input power: 28dBm (max.)\u003cbr\u003e- Output impedance: 50 ohm\u003cbr\u003e- Adjustment method: physical knob adjustment\u003cbr\u003e- Display: 0.91-inch OLED (real-time display of attenuation value)\u003cbr\u003e- Interface: Type-C (power supply interface)\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Digital Attenuator\u003cbr\u003e- 1 x Type-C Cable\u003cbr\u003e- 1 x RF Cable\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102011\/102011-01.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102011\/102011-02.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102011\/102011-03.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102011\/102011-04.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products, Audio Amplifer and Decoders","offers":[{"title":"Default Title","offer_id":41029043879985,"sku":"102011","price":53.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/1778552005-5.jpg?v=1780383832","url":"https:\/\/www.thanksbuyer.com\/products\/htool-da001-0-31-5db-adjustable-wideband-digital-rf-attenuator-module-dc-6ghz-with-0-91-inch-oled-display","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
