Description
Mimix's pHEMT technology is tested and proven
in military, space and commercial applications. Mimix's
proven workhorse, the CF001-03, is now available in
packaged form as the CFS0103-SB.
The CFS0103-SB is a high dynamic range, low
noise, pHEMT packaged in a 4-lead SOT-343 surface mount
plastic package. It is intended for many applications operating
in the 0.1 GHz to 10 GHz frequency range.
Mimix's high performance packaged pHEMTs are
ideal for use in all applications where low noise figure, high
gain, medium power and good intercept is required. The
CFS0103-SB is the perfect solution for the first or second
stage of a base station LNA due to the excellent combination
of low noise figure and linearity. It is also well suited as a
medium power driver stage in pole-top amplifiers and other
transmit functions, particularly as the low thermal resistance
allows extended power dissipation when voltage and current
are adjusted for increased power and linearity.

Considerations When Designing for Optimum
Noise Figure Using Noise Parameters
For any two-port network, the noise figure gives a
measure of the amount of noise added to a signal transmitted through that network. In this datasheet we have given
the NFmin and the corresponding optimum source resistance values for the device under various bias conditions.
NFmin represents the true minimum noise figure when the
device is presented with an impedance matching network
that transforms the source impedance typically 50 ohms to
that optimum noise matching impedance referred to as
Gopt. All stability considerations still apply, of course. If
the calculated Rollet stability factor (K) is less than 1, then
the source and load reflection coefficients must be carefully
chosen. For an accurate graphical depiction of the unstable
regions, it is best to draw stability circles.
In practice the impedance that minimizes the noise
figure is different from the impedance that minimizes the
return loss. Matching techniques such as inductive feedback
will be used to bring the noise match closer to this gain
match. An additional inherent danger of this technique is the
increased instability of the design at higher frequencies. As
the frequency increases the source inductance will also
increase, this increases the amount of feedback to the
devices source up to an oscillation level. This issue can be
reduced by carefully choosing the input and output matching topology so that the transducer gain is limited at the frequency of potential oscillation. Design of a high pass / low
pass matching network on the input and output is one solution that addresses this problem. Careful simulation is
essential using the wideband s-parameters provided and can
only be achieved through careful modeling of all components utilized in the design, including:
1. Accurate high frequency models for all surface
mount components used.
2. Accurate models of the board characteristics
including loss tangents and metal thickness.
3. Use of Via holes and via pads instead of perfect
grounds where used.
In any case if the reflection coefficient of the chosen matching network is other than Gopt, then the noise figure of the device will be greater than NFmin. The losses of
the matching circuits are also non-zero and it must be considered that the noise figure of the completed amplifier is
equal to the noise figure of the device plus the losses of the
matching network preceding the device.
The losses of the matching networks are related to
the Q of the components and associated printed circuit
board loss. In general larger gate width devices will typically have a lower Gopt as compared to smaller gate width
devices. Matching to higher impedance devices requires
very hi-Q components in order to minimize circuit losses.
The main reason for using smaller gate width devices is the
trade-off of current consumption and optimum noise performance.

Handling and Assembly Information
CAUTION! - Mimix Broadband MMIC Products contain gallium arsenide (GaAs) which can be hazardous to the human
body and the environment. For safety, observe the following procedures:
Do not ingest.
Do not alter the form of this product into a gas, powder, or liquid through burning, crushing, or chemical
processing as these by-products are dangerous to the human body if inhaled, ingested, or swallowed.
Observe government laws and company regulations when discarding this product. This product must be
discarded in accordance with methods specified by applicable hazardous waste procedures.
Life Support Policy - Mimix Broadband's products are not authorized for use as critical components in life support
devices or systems without the express written approval of the President and General Counsel of Mimix Broadband. As
used herein: (1) Life support devices or systems are devices or systems which, (a) are intended for surgical implant into
the body, or (b) support or sustain life, and whose failure to perform when properly used in accordance with instructions
for use provided in the labeling, can be reasonably expected to result in a significant injury to the user. (2) A critical
component is any component of a life support device or system whose failure to perform can be reasonably expected
to cause the failure of the life support device or system, or to affect its safety or effectiveness.
Package Attachment - This packaged product from Mimix Broadband is provided as a rugged surface mount package
compatible with high volume solder installation. Care should be taken not to apply heavy pressure to the top or base
material to avoid package damage. Vacuum tools or other suitable pick and place equipment may be used to pick and
place this part. Care should be taken to ensure that there are no voids or gaps in the solder connection so that good RF,
DC and ground connections are maintained. Voids or gaps can eventually lead not only to RF performance degradation,
but reduced reliability and life of the product due to thermal stress.
Mimix Lead-Free RoHS Compliant Program - Mimix has an active program in place to meet customer and governmental
requirements for eliminating lead (Pb) and other environmentally hazardous materials from our products. All Mimix
RoHS compliant components are form, fit and functional replacements for their non-RoHS equivalents. Lead plating of
our RoHS compliant parts is 100% matte tin (Sn) over copper alloy and is backwards compatible with current standard
SnPb low-temperature reflow processes as well as higher temperature (260°C reflow) “Pb Free” processes.
