AMMP-6222
7 to 2 GHz GaAs High Linearity LNA in SMT Package
Data Sheet
Description
Avago Technologies’ AMMP-6222 is an easy-to-use broadband, high gain, high linearity Low Noise Amplifier in a surface mount package. The wide band and unconditionally stable performance makes this MMIC ideal as a primary or sub-sequential low noise block or a transmitter or LO driver. The MMIC has 3 gain stages and a selectable pin to switch between low and high current, corresponding with low and high output power and linearity. In the high current, high output power state, it requires a 4V, 120mA supply. In the low current, low output power state, the supply is reduced to 4V, 95mA. Since this MMIC covers several bands, it can reduce part inventory and increase volume purchase options The MMIC is fabricated using PHEMT technology. The surface mount package eliminates the need of “chip & wire” assembly for lower cost. This MMIC is fully SMT compatible with backside grounding and I/Os.

AMMP-6222 Application and Usage
4V Vdd

0.1uF
Biasing and Operation
The AMMP-6222 is normally biased with a positive drain supply connected to the VDD pin through bypass capacitor as shown in Figures 19 and 20. The recommended drain supply voltage for general usage is 4V and the corresponding drain current is approximately 120mA. It is important to have 0.1uF bypass capacitor and the capacitor should be placed as close to the component as possible. Aspects of the amplifier performance may be improved over a narrower bandwidth by application of additional conjugate, linearity, or low noise (Topt) matching. For receiver front end low noise applications where high power and linearity are not often required, the AMMP6222 can be set in low current state when pin # 5 is open as shown in Figure 19. In this configuration, the bias current is approximately 90mA, 95mA and 100mA for 3V, 4V and 5V respectively. In applications where high output power and linearity are often required such as LO or transmitter drivers, the AMMP-6222 can be selected to operate at its highest output power by grounding pin # 5 as shown in Figure 20. At 5V, the amplifier can provide Psat of ~ 20dBm. The bias current in this configuration is 115mA, 120mA and 125mA for 3V, 4V and 5V respectively. Refer the Absolute Maximum Ratings table for allowed DC and thermal conditions.

Manual Assembly
• Follow ESD precautions while handling packages. • Handling should be along the edges with tweezers. • Recommended attachment is conductive solder paste. Please see recommended solder reflow profile. Neither Conductive epoxy or hand soldering is recommended. • Apply solder paste using 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. • 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. • Packages have been qualified to withstand a peak temperature of 260°C for 20 seconds. Verify that the profile will not expose device beyond these limits.

A properly designed solder screen or stencil is required to ensure optimum amount of solder paste is deposited onto the PCB pads. The recommended stencil layout is shown in Figure 23. The stencil has a solder paste deposition opening approximately 70% to 90% of the PCB pad. Reducing stencil opening can potentially generate more voids underneath. On the other hand, stencil openings larger than 100% will lead to excessive solder paste smear or bridging across the I/O pads. Considering the fact that solder paste thickness will directly affect the quality of the solder joint, a good choice is to use a laser cut stencil composed of 0.127mm (5 mils) thick stainless steel which is capable of producing the required fine stencil outline. The most commonly used solder reflow method is accomplished in a belt furnace using convection heat transfer. The suggested reflow profile for automated reflow processes is shown in Figure 24. This profile is designed to ensure reliable finished joints. However, the profile indicated in Figure 14 will vary among different solder pastes from different manufacturers and is shown here for reference only.
