I. Device Description A. General The MAX2682 miniature, low-cost, low-noise downconverter mixer is designed for low-voltage operation and is ideal for use in portable communications equipment. Signals at the RF input port are mixed with signals at the local oscillator (LO) port using a double-balanced mixer. This downconverter mixer operates with RF input frequencies between 400MHz and 2500MHz, and downconvert to IF output frequencies between 10MHz and 500MHz. The MAX2682 operates from a single +2.7V to +5.5V supply, allowing it to be powered directly from a 3-cell NiCd or a 1-cell Lithium battery. This device offers a wide range of supply currents and input intercept (IIP3) levels to optimize system performance. Additionally, this device features a low-power shutdown mode in which it typically draws less than 0.1A of supply current. Consult the Selector Guide for various combinations of IIP3 and supply current. The MAX2682 is manufactured on a high-frequency, low-noise, advanced silicon-germanium process and is offered in the space-saving 6-pin SOT23 package. B.

V. Quality Assurance Information A. Quality Assurance Contacts: Jim Pedicord (Reliability Lab Manager) Bryan Preeshl (Executive Director of QA) Kenneth Huening (Vice President) B. Outgoing Inspection Level: 0.1% for all electrical parameters guaranteed by the Datasheet. 0.1% For all Visual Defects.
C. Observed Outgoing Defect Rate: < 50 ppm D. Sampling Plan: Mil-Std-105D VI. Reliability Evaluation A. Accelerated Life Test The results of the 150C biased (static) life test are shown in Table 1. Using these results, the Failure Rate () is calculated as follows: = 1 = MTTF 1.83 (Chi square value for MTTF upper limit) 192 x 9823 x 45 x 2 Temperature Acceleration factor assuming an activation energy of 0.8eV = 10.78 x 10-8 = 10.78 F.I.T. (60% confidence level @ 25C)
This low failure rate represents data collected from Maxim's reliability qualification and monitor programs. Maxim also performs weekly Burn-In on samples from production to assure reliability of its processes. The reliability required for lots which receive a burn-in qualification is 59 F.I.T. at a 60% confidence level, which equates to 3 failures in an 80 piece sample. Maxim performs failure analysis on rejects from lots exceeding this level. The aBurn-In Schematic shows the static circuit used for this test. Maxim also performs 1000 hour life test monitors quarterly for each process. This data is published in the Product Reliability Report (RR-1M). B. Moisture Resistance Tests Maxim evaluates pressure pot stress from every assembly process during qualification of each new design. Pressure Pot testing must pass a 20% LTPD for acceptance. Additionally, industry standard 85C/85%RH or HAST tests are performed quarterly per device/package family. C. E.S.D. and Latch-Up Testing The WR22-2 die type has been found to have all pins able to withstand a transient pulse of <250V, per MilStd-883 Method 3015 (reference attached ESD Test Circuit). Latch-Up testing has shown that this device withstands a current of 50mA.
