Description
The CDQ0303-QS is a dual, ultra low-noise amplifier combining high gain, state-of-the-art noise figure and high
IP3. Utilizing Mimix's distinctive in-house GaAs fabrication advantage and matched pair technology, co-located
matched transistor die are assembled in the 4mm x 4mm
QFN package. The low-cost, surface-mount, 16 terminal,
plastic package is also lead-free.
Packaging a matched pair of ultra low-noise devices
in a single package makes the CDQ0303-QS an ideal product
for balanced amplifier implementation. It is intended for
many applications operating in the 900 MHz to 2400 MHz

Note: Typical specifications represents performance for each side of
the matched pair of transistors in the recommended application circuit
board (see page 15). It is anticipated that the pair will be used in a balanced circuit configuration, hence the matches are optimized for best
noise figure and OIP3 performance.
frequency range. It can also be used in a dual-band configuration where a single transistor is used for each band.
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
CDQ0303-QS 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.

Notes:
1. P1dB and OIP3 measurements are performed with passive biasing. Idsq is set with zero RF drive applied. As P1dB is approached, the drain current may
increase or decrease depending on frequency and DC bias point. At lower values of Idsq the device is running in a Class AB mode and current tends to rise
as P1dB is approached. As an example, at a Vds = 3.0V and Idsq = 10 mA, Id increases to 30 mA as P1dB of 16.5 is approached. This rise in current is no
longer present as Idsq approaches 60 mA.
2. Measurements made on a fixed tuned test system set for optimum noise match. Circuit losses have been de-embedded for the actual measurements.

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 reffered 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 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 / los 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. The CDQ0303-QS is a 600um gate width device has a minimum noise figure of 0.08 dB and a Gopt of Mag 0.83, Ang
36.63, making it significantly easier to match than competitive devices. Associated gain Ga is 20.82 dB.
Device Non-Linear Model - Mimix develops its own non-linear model based on its own internal device characterization. The model is verified in
different simulators and compared to the original data from which it was extracted.

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.
