APPLICATIONS Cellular infrastructure Microwave radios and very small aperture terminals (VSATs) Test equipment and sensors IF and RF designs GENERAL DESCRIPTION The HMC470A-EP is a 5-bit digital step attenuator (DSA) with a 31 dB attenuation control range in 1 dB steps. The HMC470A-EP offers excellent attenuation accuracy and high input linearity over the specified frequency range from 0.1 GHz to 3.0 GHz. However, this DSA features ACGx pins for external ac grounding capacitors to extend the operation below 100 MHz. Rev. 0 The HMC470A-EP operates with a single positive supply voltage from 3 V to 5 V and providesCMOS-/TTL-compatible parallel control interface by incorporating an on-chip driver. The HMC470A-EP comes in a RoHS compliant, compact, 3 mm x 3 mm LFCSP. Additional application and technical information can be found in the HMC470A data sheet.

Maximum Power Dissipation vs. Case Temperature THERMAL RESISTANCE Thermal performance is directly linked to printed circuit board (PCB) design and operating environment. Careful attention to PCB thermal design is required. 250 V (Class 1A) Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Only one absolute maximum rating can be applied at any one time. 1 JA is the junction to ambient air thermal resistance, and JC is the junction to case thermal resistance. Table 3.
