LMH2120UM Linear RMS Power Detector With 40 DB Dynamic Range Ic

LMH2120UM Linear RMS Power Detector with 40 dB Dynamic Range ic

APPLICATION INFORMATION

The LMH2120 is a 40 dB Linear RMS power detector particularly suited for accurate power measurements of
modulated RF signals that exhibit large peak-to-average ratios (PAR’s). The RMS detector implements the exact
definition of power resulting in a power measurement insensitive to high PAR’s. Such signals are encountered,
e.g, in LTE and W-CDMA applications. The LMH2120 has an RF frequency range from 50 MHz to 6 GHz. It
provides an output voltage that relates linearly to the RF input power in volt. Its output voltage is highly
insensitive to temperature and supply variations.

TYPICAL APPLICATION
The LMH2120 can be used in a wide variety of applications like LTE, W-CDMA, CDMA and GSM. This section
discusses the LMH2120 in a typical transmit power control loop for such applications.
Transmit-power-control-loop circuits make the transmit-power level insensitive to power amplifier (PA)
inaccuracy. This is desirable because power amplifiers are non-linear devices and temperature dependent,
making it hard to estimate the exact transmit power level. If a control loop is used, the inaccuracy of the PA is
eliminated from the overall accuracy of the transmit power level. The accuracy of the transmit power level now
depends on the RF detector accuracy instead. The LMH2120 is especially suited for transmit-power control
applications, since it accurately measures transmit power and is insensitive to temperature, supply voltage and
modulation variations.

Applications:

Multi Mode, Multi Band RF Power Control
GSM/EDGE
– CDMA/CDMA2000
– W-CDMA
– OFDMA
– LTE
Infrastructure RF Power Control

Angel Technology Electronics Co Was Founded In HongKong Since 2006, Our branch Located In The Silicon Valley Of China, Shenzhen.Angel Technology provide one stop service for electronic components,PCB and PCB Assembly(SMT).

The Mission Of  Angel Technology Electronics Co has always been to provide Quality Electronics Components To Manufacturers Worldwide.Angel-tech's vision is become the excellent electronic components supplier with the highest satisfaction between employees and customers. Early On We became the Primary channel for project closures And Inventory build-ups for Major Distributors such as Arrow Electronics and Contract Manufacturers. Angel Technology Electronics Co Has since then added Sourcing Of High Quality Components From Local Manufacturers In China.

The corporate Philosophy Policy of  Angel Technology Electronics Co is Innovation,Not limited by the inhereent thinking,always looking for new ways to meet the needs of the market.So We have specialized in providing customers with one-stop service of electronic components, PCB and SMT since 2006, helping end customers to efficiently complete the full project including BOM list procurement process etc.

Angel Technology Electronics Co Has always been Customer Driven Rather than Opportunity Driven. Meaning- Angel Tech Will Always Choose Path That is the best For Long Term Relationship With Customer Over Short Term View. It Is Why We Have One Of The Highest Customer Retention Scores Of China Based Distributors.

Prioritizes client satisfaction:

Because of our clients are at the heart of how we work,At Angel Technology Electronic Co, our goal is to provide customers with electronic components supply,PCB production, SMT assembly one-stop service.

IInnovation and creativity:
We believe that innovation is fundamental to our success and we take particular pride in regularly working closely with industry innovators and our clients to set new standards. In recent years, Angel Technology Electronics co have also started collaborating with more and more corporations to explore new technologies in smart home and PMIC.

Inventory management:
Angel Technology Electronics co provides a third-party warehousing and professional IT inventory management software for customers to achieve seamless docking. The ownership of parts can only be transferred when the customer uses parts.

Angel Technology Electronic's incoming parts have undergone rigorous inspection, and the products are stored in standard anti-static, anti-humidity, anti-high temperature, and the stock are regularly tested to make the parts safe.

Packaging transportation standard :
The parts are tested for performance during shipment, and the packaging must be waterproof, moisture-proof and shock-proof. At the same time, Angel Technology Electronics cooperates with a number of international first-class freight companies to ensure that the parts of first- and second-tier cities can be delivered at that day, and arrive the next day. The goods of third-tier cities and remote areas can be delivered at that day and arrive within two days to ensure that customer.

Angel Technology Electronics Co have been passionated about electronic components distribute and integrated solution provider since 2006. We are also a PCBA manufacturer with our own manufacotry who can better serve for customers of smart home, communication, industry, automotive electronics and medical electronics etc.
