Description
Features
The AMMC-6345 MMIC is a broadband medium power
amplifier designed for use in driving stage for transmitters that operate in various frequency bands between
20GHz and 45GHz. It can be used as a driver stage for
the AMMC-6425, 6430 and 6440 (18-27GHz, 25-32GHz
and 37-42GHz) 1W MMIC power amplifiers when linear
operation is required. At 40GHz, it provides 24dBm of
output power (P-1dB), 20dB of gain, and a 32 dBm output third order intercept (OIP3). The device has input and
output matching circuitry for use in 50 Ω environments.
The AMMC-6345 integrates a temperature compensated
RF power detection circuit that enables power detection
of 0.8V/W at 40GHz. The device operates on 5V for current supply (negative voltage only needed for Vg). It is
fabricated in a PHEMT process for exceptional power and
gain performance. For improved reliability and moisture
protection, the die is passivated at the active areas.
• Wide frequency range: 20 - 45 GHz
• High gain: 20 dB
• Power: @40 GHz, P-1dB=24 dBm
• Highly linear: OIP3=32dBm
• Integrated RF power detector
• 5.0 Volt, -0.55 Volt, 480mA operation
Applications
• Microwave Radio systems
• Satellite VSAT and DBS systems
• LMDS & Pt-Pt mmW Long Haul
• 802.16 & 802.20 WiMax BWA
• WLL and MMDS loops
• Commercial grade military
• Can be driver amplifier for the AMMC-64xx power

Note:
1. Operation in excess of any one of these conditions may result in permanent damage to this device.
Note: These devices are ESD sensitive. The following precautions are strongly recommended.
Ensure that an ESD approved carrier is used when dice are transported from one destination
to another. Personal grounding is to be worn at all times when handling these devices

4. 100% on-wafer RF test is done at frequency = 25, 30, and 38 GHz. Statistics based on 1500 part sample
5. Specifications are derived from measurements in a 50 Ω test environment. Aspects of the amplifier performance may be improved over a
more narrow bandwidth by application of additional conjugate, linearity, or power matching.

Biasing and Operation
Assembly Techniques
AMMC-6345 has quite flexible drain biasing conditions.
Recommended quiescent DC bias condition for optimum
power and linearity performances is Vd=5 volts with
Vg set for Id=480 mA. For high gain applications, the
AMMC-6345 can be biased at Vd=3V. Minor improvements in performance are possible depending on the
application. The drain bias voltage range is 3 to 5.5V. A
single DC gate supply connected to Vg will bias all gain
stages. Muting can be accomplished by setting Vg to the
pinch-off voltage Vp.
The backside of the MMIC chip is RF ground. For microstrip applications the chip should be attached directly
to the ground plane (e.g. circuit carrier or heatsink) using
electrically conductive epoxy[1].
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
emerging from the RF output port. The detected voltage
is given by :
V = (V ref − V det )− V ofs
V
where ref is the voltage at the DET _ R port, V det is a voltV
age at the DET _ O port, and ofs is the zero-input-power
offset voltage. There are three methods to calculate :
V
1. ofs can be measured before each detector measurement (by removing or switching off the power source
and measuring ). This method gives an error due to
temperature drift of less than 0.01dB/50°C.
V
2. ofs can be measured at a single reference temperature.
The drift error will be less than 0.25dB.
V
3. ofs 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 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.
For best performance, the topside of the MMIC should be
brought up to the same height as the circuit surrounding
it. This can be accomplished by mounting a gold plate
metal shim (same length and width as the MMIC) under
the chip which is of correct thickness to make the chip
and adjacent circuit the same height. The amount of
epoxy used for the chip and/or shim attachment should
be just enough to provide a thin fillet around the bottom
perimeter of the chip or shim. The ground plain should
be free of any residue that may jeopardize electrical or
mechanical attachment.
The location of the RF bond pads is shown in Figure
12. Note that all the RF input and output ports are in a
Ground-Signal configuration.
RF connections should be kept as short as reasonable to
minimize performance degradation due to undesirable
series inductance. A single bond wire is normally sufficient for signal connections, however double bonding
with 0.7 mil gold wire or use of gold mesh[2] is recommended for best performance, especially near the high
end of the frequency band.
Notes:
1. Ablebond 84-1 LM1 silver epoxy is recommended.
