AVAGO AMMP-6425

AMMP-6425
18-28 GHz 1W Power Amplifier in SMT Package
Data Sheet
Description
Features
The AMMP-6425 MMIC is a broadband 1W power
amplifier in a surface mount package designed for use
in transmitters that operate in various frequency bands
between 18GHz and 28GHz. At 25GHz, it provides 31dBm
of output power (P-1dB) and 25dB of small-signal gain
from a small easy-to-use device. The device has input
and output matching circuitry for use in 50Ω environments. The AMMP-6425 also integrates a temperature
compensated RF power detection circuit that enables
power detection of 0.25V/W. DC bias is simple and the
device operates on widely available 5V for current supply
(negative voltage only needed for Vg). It is fabricated in
a PHEMT process for exceptional power and gain performance.

Notes:
1. Operation in excess of any one of these conditions may result in permanent damage to this device.
2. Combinations of supply voltage, drain current, input power, and output power shall not exceed PD.
3. When operate at this condition with a base plate temperature of 85°C, the median time to failure (MTTF) is significantly reduced.
4. These ratings apply to each individual FET
5. Junction operating temperature will directly affect the device MTTF. For maximum life, it is recommended that junction temperatures be
maintained at the lowest possible levels.

Notes:
6. Assume SnPb soldering to an evaluation RF board at 85°C base plate temperatures. Worst case is at saturated output power when DC power
consumption rises to 5.5W with 1.58W RF power delivered to load. Power dissipation is 3.92W and the temperature rise in the channel is 69.8
°C. In this condition, the channel temperature reached at the maximum operational channel temperature of 155°C. To maintain the maximum
operational temperature below 155°C, the base plate temperature must be maintained below 85°C

Notes:
1. Small/Large -signal data measured in packaged form on a 2.4mm connecter based evaluation board at TA = 25°C.
2. This final package part performance is verified by a functional test correlated to actual performance at one or more frequencies
3. Specifications are derived from measurements in a 50Ω test environment. Aspects of the amplifier performance may be improved over a
narrower bandwidth by application of additional conjugate, linearity, or power matching.
4. Pre-assembly into package performance verified 100% on-wafer published specifications at Frequencies=18, 23, and 28GHz.
5. The Gain and P1dB tested at 18, 23 and 28 GHz guaranteed with measurement accuracy ±1.5dB for Gain and P1dB, except Gain at 18 GHz with
measurement accuracy ±1.8dB.

AMMP-6425 Application and Usage
Recommended quiescent DC bias condition for optimum
power and linearity performances is Vdd=5 volts with Vg
(-1.1V) set for Idq=650 mA. Minor improvements in performance are possible depending on the application.
The drain bias voltage range is 3 to 5V. A single DC gate
supply connected to Vgg will bias all gain stages. Muting
can be accomplished by setting Vgg to the pinch-off
voltage Vp.
emerging from the RF output port. The detected voltage
is given by :
A simplified schematic for the AMMP6425 MMIC die is
shown in Figure 12. The MMIC die contains ESD and over
voltage protection diodes for Vg, and Vdd terminals.
The package diagram for the recommended assembly
is shown in Figure 13. In finalized package form, ESD
diodes protect all possible ESD or over voltage damages
between Vgg and ground, Vgg and Vdd, Vdd and ground.
Typical ESD diode current versus diode voltage for 11connected diodes in series is shown in Figure 14. Under
the recommended DC quiescent biasing condition at
Vds=5V, Ids=650mA, Vgg=-1V, typical gate terminal
current is approximately 0.3mA. If an active biasing
technique is selected for the AMMP6425 MMIC PA DC
biasing, the active biasing circuit must have more than
10-times higher internal current that the gate terminal
current.
There are three methods to calculate Vofs :
An optional output power detector network is also
provided. The differential voltage between the Det-Ref
and Det-Out pads can be correlated with the RF power
DET_R
V = (V ref − V det ) − V ofs
where Vref is the voltage at the DET_R port, Vdet is a
voltage at the DET_0 port, Vofs and is the zero-inputpower offset voltage.
1. Vofs can be measured before each detector
measurement (by removing or switching off the
power source and measuring Vref - Vdet). This method
gives an error due to temperature drift of less than
0.01dB/50°C.
2. Vofs can be measured at a single reference
temperature. The drift error will be less than 0.25dB.
3. Vofs can either be characterized over temperature and
stored in a lookup table, or it can be measured at two
temperatures and a linear fit used to calculate Vofs at
any temperature. This method gives an error close to
the method #1.
The RF ports are AC coupled at the RF input to the first
stage and the RF output of the final stage. No ground
wired are needed since ground connections are made
with plated through-holes to the backside of the device.

Note:
No RF performance degradation is seen due to ESD up to 200V HBM and 60V MM. The DC characteristics in general show increased leakage at
lower ESD discharge voltages. The user is reminded that this device is ESD sensitive and needs to be handled with all necessary ESD protocols.

The PCB material and mounting pattern, as defined in the
data sheet, optimizes RF performance and is strongly recommended. An electronic drawing of the land pattern

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 15b. 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 16. This profile is
designed to ensure reliable finished joints. However, the
profile indicated in Figure 1 will vary among different
solder pastes from different manufacturers and is shown
here for reference only.
