High Directivity Monolithic Amplifier Die 50Ω MNA-5A-D+ 0.5 to 4.5 GHz The Big Deal • Integrated matching, DC Blocks and bias circuits • Excellent Active Directivity • Operates over 2.8-5V Product Overview MNA-5A-D+ is a wideband PHEMT based MMIC amplifier die with high active Directivity. MNA integrates the entire matching network and majority of the bias circuit inside the die, reducing the need for complicated external circuits. This approach makes the MNA amplifier die extremely straightforward to use. This design operates on a single 2.8 to 5V supply, is well matched for 50Ω. Key Features Feature Advantages Excellent Active Directivity (Isolation- Gain) 17-23 dB Ideal for use as a buffer amplifier minimizing interaction of adjacent circuits Integrates DC blocks and RF choke Minimizes external components, component count and circuit area. Single +2.8 to +5V operation Amplifier can be used at low voltage such as +3V or standard +5V. +5V operation results in higher P1dB and OIP3. Unpackaged die Enables the user to integrate the amplifier directly into hybrids. Notes A.

Storage Dice should be stored in a dry nitrogen purged desiccators or equivalent. 2. ESD MMIC PHEMT amplifier dice are susceptible to electrostatic and mechanical damage. Die are supplied in antistatic protected material, which should be opened in clean room conditions at an appropriately grounded anti-static worksta tion. Devices need careful handling using correctly designed collets, vacuum pickup tips or sharp antistatic tweezers to deter ESD damage to dice. 3. Die Attach The die mounting surface must be clean and flat. Using conductive silver filled epoxy, recommended epoxies are DieMat DM6030HK-PT/H579 or Ablestik 84-1LMISR4. Apply sufficient epoxy to meet required epoxy bond line thickness, epoxy fillet height and epoxy coverage around total die periphery. Parts shall be cured in a nitrogen filled atmosphere per manufacturer’s cure condition. It is recommended to use antistatic die pick up tools only. 4. Wire Bonding Bond pad openings in the surface passivation above the bond pads are provided to allow wire bonding to the dice gold bond pads. Thermosonic bonding is used with minimized ultrasonic content. Bond force, time, ultrasonic power and temperature are all critical parameters. Suggested wire is pure gold, 1 mil diameter. Bonds must be made from the bond pads on the die to the package or substrate. All bond wires should be kept as short as low as reasonable to minimize performance degradation due to undesirable series inductance.
