2.0-18.0 GHz GaAs MMIC Low Noise Amplifier May 2006 - Rev 08-May-06 CMM4000 Chip Device Layout Features Self Bias Architecture On-Chip Drain Bias Coil/DC Blocking 9.0 dB Small Signal Gain 4.5 dB Noise Figure +19.0 dBm P1dB Compression Point 100% Visual Inspection to MIL-STD-883 Method 2010 General Description Mimix Broadband’s 2.0-18.0 GHz GaAs MMIC distributed low noise amplifier has a small signal gain of 9.0 dB with a noise figure of 4.5 dB across the band. This MMIC uses Mimix Broadband’s 0.3 µm GaAs PHEMT device model technology, and is based upon optical beam lithography to ensure high repeatability and uniformity. The chip has surface passivation to protect and provide a rugged part with backside via www.DataSheet4U.com holes and gold metallization to allow either a conductive epoxy or eutectic solder die attach process. This device is well suited for fiber optic, microwave radio, military, space, telecom infrastructure, test instrumentation and VSAT applications.

Bias is nominally Vd=5V, I=115mA. Additionally there are three source resistors on chip, 13, 12 and 8.5 Ohms. One of these must be bonded to ground. Typically 12 Ohms is bonded to ground to achieve performance as shown. Bonding to one of the other resistors or any or all in parallel may allow additional performance adjustment. App Note [2] Bias Arrangement - Each DC pad (Vd) needs to have DC bypass capacitance (~100-200 pF) as close to the device as possible. Additional DC bypass capacitance (~0.01 uF) is also recommended. MTTF Table (TBD) (Thermal Resistance (Rth) is 82ºC/W) These numbers were calculated based on accelerated life test information and thermal model analysis received from the fabricating foundry.
