Overview
ATTENUATORS - SMT 5 5 - 170 HMC540LP3 / 540LP3E v00.
0605 1 dB LSB GaAs MMIC 4-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 5.
5 GHz Typical Applications Features The HMC540LP3 / HMC540LP3E is ideal for both RF 1 dB LSB Steps to 15 dB and IF applications: ± 0.
2 dB Typical Step Error • Cellular Infrastructure Low Insertion Loss: 1 dB • ISM, MMDS, WLAN, WiMAX, WiBro • Microwave Radio & VSAT • Test Equipment and Sensors Functional Diagram High IP3: +50 dBm Single Control Line Per Bit TTL/CMOS Compatible Control Single +5V Supply 3x3 mm SMT Package E General Discription The HMC540LP3 & HMC540LP3E are broadband T 4-bit GaAs IC digital attenuators in low cost leadless surface mount packages.
This single positive control line per bit digital attenuator utilizes off chip AC E ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications.
Covering DC to 5.
5 GHz, the insertion loss is less Lthan 1 dB typical.
The attenuator bit values are 1 (LSB), 2, 4 and 8 dB for a total attenuation of 15 dB.
Attenuation accuracy is excellent at ± 0.
2 dB typical step error.
The attenuator also features a IIP3 of +50 OdBm.
Four TTL/CMOS control inputs are used to select each attenuation state.
A single Vdd bias of +5V is required.
S Electrical Specifications, TA = +25° C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted) Parameter B Insertion Loss Frequency (GHz) Min.
