PGA-105+ 是由 Mini-Circuits 公司生产的一款高性能、低噪声放大器(Low Noise Amplifier,LNA),专为广泛的无线通信和广播应用而设计。该设备在 40 MHz 到 2.6 GHz 的频率范围内提供卓越的性能,适用于各种场景,如有线电视(CATV)、长期演进技术(LTE)、直接广播卫星(DBS)、无线局域网(WLAN)和多点分配系统(MMDS)。
PGA-105+ 采用表面安装技术(SMT)封装,适合现代电子产品的紧凑设计要求。其 50Ω 输入和输出阻抗匹配,使其易于集成到各种系统中,无需额外的匹配网络。
PGA-105+ 的噪声系数仅为 1.9 dB,这使得它在信号接收和处理方面具有极高的灵敏度和准确性。低噪声系数对于确保信号质量尤其重要,特别是在长距离传输或弱信号环境中。
该放大器提供了 15.9 dB 的增益,这意味着它可以显著提高输入信号的强度,从而改善系统的整体性能和可靠性。这种高增益使得 PGA-105+ 非常适合需要强化弱信号的应用场景。
PGA-105+ 支持从 40 MHz 到 2.6 GHz 的宽频带范围,这使得它可以应用于多种无线通信标准和技术。这种灵活性使得该设备成为多种系统的理想选择,无论是传统的广播还是现代的移动通信网络。
该设备能够在 -40℃ ~ +85℃ 的广泛温度范围内正常工作,这使得它适用于各种环境条件下的应用,从室内设备到户外基站。这种耐温能力确保了设备在极端温度条件下仍能保持稳定运行。
在 CATV 系统中,PGA-105+ 可以用来增强电视信号,从而提高图像和声音质量。其低噪声和高增益特性使得它特别适合用于长距离信号传输。
在 LTE 网络中,PGA-105+ 可以用于基站和用户设备中,以提高信号强度和减少噪声干扰。其宽频带支持使得它可以适应不同频段的需求。
对于 DBS 应用,PGA-105+ 可以用来增强从卫星接收到的信号,从而提高电视和数据服务的质量。其高增益和低噪声特性对于确保清晰的视频和音频传输至关重要。
在 WLAN 系统中,PGA-105+ 可以用于无线接入点(AP)和客户端设备,以提高无线信号的强度和覆盖范围。其宽频带支持使得它可以适应 802.11ac 和 802.11ax 等标准。
对于 MMDS 应用,PGA-105+ 可以用来增强从基站发出的信号,从而提高数据传输速率和服务质量。其低噪声和高增益特性对于确保可靠的数据传输至关重要。
Mini-Circuits 的 PGA-105+ 是一款功能强大、性能优异的低噪声放大器,广泛应用于各种无线通信和广播领域。其卓越的噪声性能、宽频带支持、宽工作温度范围以及高增益,使得它成为多种系统的理想选择。无论是在传统的有线电视系统还是现代的移动通信网络中,PGA-105+ 都能提供可靠、高效的信号放大解决方案。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
