AMMP-6425
18-28 GHz 1W Power Amplifier in SMT Package
Data Sheet
Description
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 environ-
ments. 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 perfor-
mance.

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.
