Device Description A. General The MAX2391 fully integrated direct-conversion receiver IC is designed specifically for W-CDMA applications. With the MAX2395, the MAX2391 forms a complete single-mode W-CDMA radio chipset. The MAX2391 provides a complete antenna-to-baseband solution for the 3GPP W-CDMA FDD receiver (2110MHz to 2170MHz, 3.84Mcps), eliminating the use of an off-chip IF SAW filter, as well as external RX LO generation and synthesis. The MAX2391 receiver ICs have over 90dB of dynamic gain control, and a receive sensitivity of -112dBm referred to LNA input. The receiver consists of an ultra-low current low-noise amplifier (LNA) with on-chip output matching and a two-step gain control. The zero-IF demodulator has a differential circuit topology for minimum LO leakage to the receiver’s input. The channel selectivity is done completely in the baseband section of the receiver with an on-chip lowpass filter. The AGC section has over 50dB of gain control range. LO quadrature generation is done onchip through a divide-by-2 prescaler. The DC offset cancellation in the I/Q baseband channels is done fully on-chip using a DC servo loop. To quickly correct for large DC offset transients in minimal time, very fast settling time is obtained by optimization of the DC-offset cancellation circuit’s time constant. The MAX2391 includes a 3-wire serial bus for PLL programming and for configuring the different receiver modes. It also includes a SHDN pin for full device shutdown. The MAX2391is fabricated using an advanced high-frequency SiGe BiCMOS process. The IC operates from a single +2.7V to +3.3V supply and is housed in a small 28-pin leadless QFN-EP package (5mm × 5mm).

Quality Assurance Contacts: Jim Pedicord (Manager, Reliability Operations) Bryan Preeshl (Executive Director of QA) Kenneth Huening (Vice President) B.

Reliability Evaluation A. Accelerated Life Test The results of the 150°C biased (static) life test are shown in Table 1. Using these results, the Failure Rate (λ) is calculated as follows: λ= 1 = MTTF 1.83 192 x 9823 x 99 x 2 (Chi square value for MTTF upper limit) Temperature Acceleration factor assuming an activation energy of 0.8eV λ = 4.90 x 10-9 λ = 4.90 F.I.T. (60% confidence level @ 25°C) 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 attached Burn-In Schematic #06-7084 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-B2A). 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 85°C/85%RH or HAST tests are performed quarterly per device/package family. C. E.S.D. and Latch-Up Testing The WC17-1 die type has been found to have all pins able to withstand a transient pulse of <200V, per MilStd-883 Method 3015 (reference attached ESD Test Circuit). Latch-Up testing has shown that this device withstands a current of ±250mA.
