LTC5587IDD: RF Power Detector——6GHz RMS Power Detector with Digital Outputs 

Basic Information: 

Model Number: LTC5587IDD 

Package: DFN-12 

Type: RF Power Detector 

The LTC5587IDD is a 10MHz to 6GHz, low-power, monolithic, precision RMS power detector with an integrated 12-bit serial analogue-to-digital converter (ADC). The RMS detector uses a proprietary technique to accurately measure the RF power of modulated signals with up to 12dB crest factor. The detection range is -34dBm to 6dBm for a 2.14GHz input frequency, and the serial digital output of the detector is a 12-bit word value proportional to the RF signal power in dBm.

Here are the product details for the LTC5577IUF: 

Model No.: LTC5577IUF 

Package: QFN- 16 

Type: RF Mixer 

300MHz to 6GHz, RF Mixer/Active Mixer, QFN-16 

The LTC5577IUF active mixers are optimised for RF downconversion applications requiring high input signal processing capability and wide bandwidth. The wideband IF output uses an external resistor to set the output impedance, providing the flexibility of direct matching to differential IF loads such as filters and amplifiers. Although characterised and specified for a 100Ω differential output impedance, the device operates with output impedances from 50Ω to 400Ω, with high gain and reduced IIP3 and P1dB at higher impedance levels.F outputs can be used at frequencies up to 1.5GHz.

LTC5577IUF Product Features: 

+30dBm IIP3 

+15dBm Input P1dB 

0dB conversion gain 

Wideband Differential IF Output 

Very Low 2 x 2 and 3 x 3 Spurious 

IF Frequency Range up to 1.5GHz 

Low LO-RF Leakage 

LO Inputs 50Ω Matched at Stop 

-40ºC to 105ºC Operating Temperature (TC) Very small solution form factor

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
