It is housed in the Avago Technologies industry-leading and revolutionary sub-miniature chip scale package (GaAsCap wafer scale leadless package) which is small and ultra thin yet can be handled and placed with standard pick and place assembly equipment. The VMMK-33 provides a typical gain of db with good linearity of.9 dbm typical IIP3 and input and output return losses and can be operated from 3 to power supply. It is fabricated using Avago Technologies unique.5 μm E-mode PHEMT technology which eliminates the need for negative gate biasing voltage.

7 VMMK-33 Applications Information Biasing and Operation The VMMK-33 is biased with a positive supply connected to the output pin Vd through an external user supplied bias decoupling network. Typical bias is at ma. The on state also requires that the input port of the VMMK-33 also be biased at for normal gain operation. V on the input puts the VMMK-33 in the off state. An example of simple user supplied bias tees is shown in Figure 13. The output bias decoupling network feeding Vdd consists of a shunt 6. nh inductor. At the input, a 1 Kohm resistor is needed to feed the power-down control voltage. The input and output dc blocking capacitors are each 1 pf. The on and off S Parameters shown in the preceding tables reflect the operation of the circuit shown in Figure 1. Figure 13.

VMMK-33 Demo Board BOM Component DUT C1 C R1 C5 C6 L1 Value VMMK-33 1 pf 1 pf 1 kohm.1 mf 1 pf 6. nh The input and output bias decoupling network can be easily constructed using small surface mount components. The value of the shunt inductors can have a major effect on both low and high frequency operation. The demo board uses small value inductors that have self resonant frequencies higher than the maximum desired frequency of operation. If the self-resonant frequency of the inductor is too close to the operating band, the value of the inductor will need to be adjusted so that the selfresonant frequency is significantly higher than the highest frequency of operation. Typically a passive component company like Murata does not specify S parameters at frequencies higher than 5 or 6 GHz for larger values of inductance making it difficult to properly simulate amplifier performance at higher frequencies. It has been observed that the Murata LQW15AN series of inductors actually works quite well above their normally specified frequency. The parallel combination of the 1 pf and.1 mf bypass capacitors provide a low impedance in the band of operation and at lower frequencies and should be placed as close as possible to the inductor. The low frequency bypass provides good rejection of power supply noise and also provides a low impedance termination for third order low frequency mixing products that will be generated when multiple in-band signals are injected into any amplifier.

8 S Parameter Measurements The S-parameters are measured on a.16 inch thick RO3 printed circuit test board, using G-S-G (ground signal ground) probes. Coplanar waveguide is used to provide a smooth transition form the probes to the device under test. The presence of the ground plane on top of the test board results in excellent grounding at the device under test. A combination of SOLT (Short Open Load Thru) and TRL (Thru Reflect Line) calibration techniques are used to correct for the effects of the test board, resulting in accurate device S parameters. Package and Assembly Note For detailed description of the device package, handling and assembly, refer to Application Note 537. ESD Precautions Note: These devices are ESD sensitive. The following precautions are strongly recommended. Ensure that an ESD approved carrier is used when die are transported from one destination to another. Personal grounding is to be worn at all times when handling these devices. For more detail, refer to Avago application note AR: Electro-static Discharge Damage and Control.

Recommended SMT Attachment The VMMK Packaged Devices are compatible with high volume surface mount PCB assembly processes. Manual Assembly for Prototypes 1. Follow ESD precautions while handling packages.. Handling should be along the edges with tweezers or from topside if using a vacuum collet. 3. Recommended attachment is solder paste. Please see recommended solder reflow profile. Conductive epoxy is not recommended. Hand soldering is not recommended.. Apply solder paste using either a stencil printer or dot placement. The volume of solder paste will be dependent on PCB and component layout and should be controlled to ensure consistent mechanical and electrical performance. Excessive solder will degrade RF performance. 5. Follow solder paste and vendor s recommendations when developing a solder reflow profile. A standard profile will have a steady ramp up from room temperature to the pre-heat temp to avoid damage due to thermal shock. 6. Packages have been qualified to withstand a peak temperature of 6 C for to sec. Verify that the profile will not expose device beyond these limits. 7. Clean off flux per vendor s recommendations.. Clean the module with Acetone. Rinse with alcohol. Allow the module to dry before testing. 9
