18...31.5 GHz LNA in Plastic<br />
Package<br />
Richardson RFPD, Inc. announced the<br />
availability and full design support capabilities<br />
for a versatile low noise amplifier<br />
from Macom Technology Solutions Inc.<br />
The MAAL-011129 is an easy-to-use threestage<br />
low noise amplifier with high gain and<br />
broadband 50 ohm match. It is designed for<br />
operation from 18 to 31.5 GHz and housed<br />
in a lead-free 2 mm 8-lead PDFN plastic<br />
package. The MAAL-011129 has an integrated<br />
active bias circuit and bias tee to allow<br />
direct connection to V DD without external<br />
chokes or DC blocks. The bias current is<br />
set by a simple external resistor, RB, so the<br />
user can customize the power consumption.<br />
The MAAL-011129 offers a surface-mount,<br />
easy-to-use, low noise amplifier solution<br />
that is well suited to diverse receiver applications,<br />
including V SAT , point-to-point and<br />
24 GHz ISM.<br />
Additional key features of the MAAL-<br />
011129 include:<br />
• Noise figure: 2.5 dB @ 24 GHz<br />
• High gain: 23 dB @ 24 GHz<br />
• 50 ohm match on input and output<br />
• Single voltage bias: 3 to 5 V range<br />
• Current adjustable from 1 to 80 mA<br />

High Gain Driver Offers Low<br />
Power Consumption<br />
RFMW announces design and sales support<br />
for a high gain and high peak-power driver<br />
amplifier. The Qorvo QPA9121 provides 28<br />
dB of gain with up to ½ Watt of RF power<br />
from 2300 to 5000 MHz. Drawing only 95<br />
mA from a single, 5 V supply, the QPA9121’s<br />
low power consumption provides solutions<br />
in wireless infrastructure, repeaters and distributed<br />
antenna systems. OIP3 is 32 dBm<br />
from this 50 ohm, internally matched device<br />
packaged in a 3 x 3 mm QFN.<br />

GaN PA Supports Ka-Band<br />
Satcom<br />
RFMW announces design and sales support<br />
for a high frequency power amplifier from<br />
Qorvo. The Qorvo QPA22<strong>10</strong>D offers 2.5 W<br />
of linear power at 25 dBc IMD3 with small<br />
signal gain of 25 dB. This linear power and<br />
high gain are ideal for Ka-Band satellite<br />
communication systems operating within<br />
27 to 31 GHz as well as mmWave 5G infrastructure<br />
radios. The QPA22<strong>10</strong>D has a saturated<br />
output power of 7 Watts. Drawing 200<br />
mA from a 20 V supply, this PA is offered<br />
in a 2.74 x 1.432 mm Die.<br />

90 W Transistor Offers High<br />
Efficiency and High Gain<br />
RFMW announced design and sales support<br />
for a high gain, GaN transistor with<br />
excellent efficiency. The Qorvo QPD0060<br />
spans DC to 2.7 GHz with 90 W of P3dB<br />
output power and maximum drain efficiency<br />
of 74.7%. Linear gain is 19.5 dB and<br />
efficiency-tuned P3dB gain is 21.5 dB. Designed<br />
for 48 V operation, the QPD0060 serves<br />
wireless infrastructure, active antenna<br />
systems, military & commercial radar, land<br />
mobile and military radio communications<br />
and test instrumentation. Functional as either<br />
a driver or final stage it’s both CW and<br />
pulse capable. Offered in a plastic overmold,<br />
SMT package.<br />

6 GHz Low Threshold Limiter<br />
Module<br />
RFMW announced design and sales support<br />
for Skyworks SKY16601-555LF PIN diode<br />
limiter module covering the frequency range<br />
of 0.5 to 6 GHz. The SKY16601-555LF<br />
addresses the need for passive protection<br />
of LNAs in microwave receiver applications.<br />
It is a fully integrated PIN diode, lowthreshold<br />
limiter module in a 2.5 x 2.5 mm<br />
SMT package. Capable of handling 230 W<br />
pulsed power, insertion loss is only 0.1 dB<br />
while return loss is specified at 27.5 dB.<br />
Typical threshold level is 11 dBm with a flat<br />
leakage power of 13 dBm at 20 dBm input.<br />
