FEATURES Attenuation range: 1 d B LSB steps to 31 d B Insertion loss: 1.7 d B typical at 3 GHz Excellent attenuation accuracy: 0.3 d B typical High Input linearity 0.1d B pression (P0.1d B): 27 d Bm typical Third-order intercept (IP3): 48 d Bm typical High power handling: 27 d Bm Low phase shift: 27° at 3 GHz Single-supply operation: 3 V to 5 V CMOS-/TTL-patible parallel control 16-lead, 3 mm × 3 mm LFCSP package APPLICATIONS Cellular infrastructure Microwave radios and very small aperture terminals (VSATs) Test equipment and sensors IF and RF designs FUNCTIONAL BLOCK DIAGRAM 16 V5 15 V4 14 V3 13 V2 VDD 1 RF1 2 NIC 3 ACG1 4 ACG2 5 ACG3 6 ACG4 7 ACG5 8 1d B 2d B 4d B 8d B 16d B HMC470A Figure 1. 12 V1 11 RF2 10 NIC 9 ACG6 PACKAGE BASE GND 14806-001 GENERAL DESCRIPTION The HMC470A is a 5-bit digital attenuator with a 31 d B attenuation control range in 1 d B steps. The HMC470A offers excellent attenuation accuracy and high input linearity over the specified frequency range from 100 MHz to 3 GHz. However, this digital attenuator features ACG pins for external ac grounding capacitors to extend the operation below 100 MHz. The HMC470A operates with a single positive supply voltage from 3 V to 5 V and provides CMOS-/TTL-patible parallel control interface by incorporating an on-chip driver. The HMC470A es in a Ro HS pliant, pact, 3 mm × 3 mm LFCSP package. Rev. A Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
