The testing is designed to simulate the worst-case environments the product may experience during assembly, test and life in the end user application. The device was electrically tested to the appropriate catalog specifications. 1.1 General Description The 16L 3x3mm QFN package uses a copper alloy lead frame. The lead frame is silver plated internally to enable gold wire bonding. The MMIC device is attached to the paddle using conductive epoxy. The device interconnection is performed using 1 mil gold ball bonds. The part is encapsulated using Sumitomo EME G700 or equivalent epoxy encapsulating compound. The leads are finished with 100% Matte Sn plating. The HMC424LP3 & HMC424LP3E are broadband 6-bit GaAs IC digital attenuators in low cost leadless surface mount packages. Covering DC to 13 GHz, the insertion loss is less then 4 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenuation accuracy is excellent at ± 0.5 dB typical step error with an IIP3 of +32 dBm. Six control voltage inputs, toggled between 0 and -5V, are used to select each attenuation state. A single Vee bias of -5V allows operation at frequencies down to DC.

NOTES Package Type: 6L LP2, 16L LP3 Package Style: 16L 3x3mm QFN Package Product: HMC424LP3E QTR: 11003 Rev: 02 3.0 Test Procedures 3.1 Package Environmental Tests These tests are designed to demonstrate that the HMC424LP3E utilizing the 16L3x3mm QFN surface mount plastic encapsulated package assembled at ASE, Korea is capable of maintaining the specified parameters throughout their useful life under rated operating conditions. 3.1.1 Initial Characteristics - 160 HMC424LP3E devices were electrically tested for DC and critical RF parameters. These tests are performed at ambient temperature (+25°C). This test was performed at Hittite. There were no failures in this test. 3.1.2 MSL1 260°C Reflow Preconditioning – 160 devices from 3.1.1 were subjected to 168 hours at 85°C/ 85% RH then a reflow simulation at a peak temperature of 260°C for 3 passes (see Figure 1 for profile). 3.1.3 Temperature Cycle - 80 devices from 3.1.2 were subjected to 500 cycles of non-operating temperature cycling from -65°C to 150°C. This test is performed at Hittite. 3.1.4 Final Electrical Test - 80 devices from 3.1.3 were electrically tested at ambient temperature to DC and critical RF parameters. Any out of specification parameter is considered a failure. This test was performed at Hittite. There were no relevant failures in this test. 3.1.5 Autoclave - 80 devices from 3.1.2 were subjected to 96 hours of humidity (100%), temperature (121°C) and pressure (15 PSIG). This test is performed at Hittite using an Espec environmental chamber. 3.1.6 Final Electrical Test - 80 devices from 3.1.5 were electrically tested at ambient temperature to DC and critical RF parameters. Any out of specification parameter is considered a failure. This test was performed at Hittite within 48 hours after removal from the chamber. There were no relevant failures in this test.
