Product details
Overview
CMD180 from Qorvo is a GaAs pHEMT MMIC low-noise amplifier (LNA) optimized for 2–6 GHz broadband operation, featuring 17.5 dB small-signal gain, 0.65 dB noise figure at 3.5 GHz, and +30 dBm OIP3, used in receiver front-ends for radar and communications systems.
For engineers reviewing the CMD180 datasheet, pinout, applications, or equivalent options, key selection criteria include its 50 Ω input/output match, DC bias requirements (VDD = +5 V, IDQ = 60 mA), and guaranteed performance across military temperature range (–40 °C to +85 °C).
Technical Context
The CMD180 employs a single-stage GaAs pHEMT design with on-chip DC blocking capacitors and RF chokes, enabling 50 Ω matched operation without external matching components at 2–6 GHz. It operates from a single +5 V supply and integrates internal bias network for stable quiescent current.
Its cascode topology delivers high reverse isolation (>30 dB) and robust linearity, supporting wideband receiver applications where intermodulation suppression and low added noise are critical-particularly in S-band and C-band radar receivers and 5G fixed wireless access front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 2–6 GHz: fully characterized and specified bandwidth for LNA operation without retuning. |
| Small-Signal Gain | 17.5 dB at 3.5 GHz: enables high sensitivity in cascaded receiver chains with minimal additional gain stages. |
| Noise Figure | 0.65 dB at 3.5 GHz: directly supports detection of weak signals in radar and spectrum monitoring systems. |
| OIP3 | +30 dBm at 3.5 GHz: ensures strong two-tone intermodulation immunity in dense RF environments. |
| Supply Voltage | +5 V DC: compatible with standard system power rails and simplifies biasing versus dual-supply LNAs. |
| Quiescent Current | 60 mA: defines thermal load and power budget for compact RF module integration. |
Pinout & Package
Package: 3 mm × 3 mm, 16-pin QFN with exposed paddle (RoHS-compliant, moisture-sensitive level 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 (Pins 1, 2, 3) | Drain supply input | Parallel connection points for +5 V supply; low-inductance path required for RF stability. |
| RF_IN (Pin 5) | Input RF port | 50 Ω matched input; DC-coupled with internal blocking capacitor-no external DC block needed. |
| RF_OUT (Pin 12) | Output RF port | 50 Ω matched output; DC-coupled with internal blocking capacitor-enables direct connection to mixer or IF stage. |
| GND (Pins 4, 6–11, 13–16) | Ground reference | All ground pins must be soldered to solid thermal/RF ground plane; exposed paddle is primary thermal path. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates need for external gate resistors or bias tees-reduces BOM count and layout area. |
| On-chip DC blocking | Enables AC-coupled system interfaces without discrete capacitors at RF_IN/RF_OUT-improves broadband repeatability. |
| High reverse isolation | >30 dB across 2–6 GHz-prevents LO leakage feedback and oscillator pulling in transceiver designs. |
| Military-grade temp range | Specified from –40 °C to +85 °C-qualified for deployment in outdoor radar enclosures and avionics subsystems. |
Applications
| Radar Receiver Front-End | 5G Fixed Wireless Access (FWA) CPE |

IC Role / Device Role / Timing Role: Low-noise receive amplifier in active antenna unit (AAU) RF front-end. Use Value: 17.5 dB gain and 50 Ω match simplify impedance control across variable environmental conditions and reduce calibration overhead. |
| Electronic Warfare (EW) Signal Intelligence | Test & Measurement Broadband Receiver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| QPL9057 | Higher gain (19.5 dB), lower NF (0.55 dB), but narrower bandwidth (3.3–4.2 GHz); requires external gate bias. | Optimized for 5G NR n77/n78 bands only-not suitable for full 2–6 GHz sweep. | Prefer QPL9057 when targeting narrowband 3.5 GHz 5G infrastructure with tighter NF budget. |
| MACOM MAAL-011078 | Wider bandwidth (1–8 GHz), higher NF (0.9 dB), same +5 V supply; no integrated bias network. | Requires external gate resistor and DC blocking-increases layout complexity and component count. | Select MAAL-011078 only if system-level bandwidth extension beyond 6 GHz is mandatory and NF tolerance >0.7 dB. |
Compared with QPL9057 and MAAL-011078, the CMD180 uniquely balances full 2–6 GHz coverage, integrated biasing, and sub-0.7 dB NF-making it optimal for wideband military radar and multi-standard test equipment where design simplicity and broadband fidelity are jointly critical.

FAQ
What is the operating temperature range specified for the CMD180?
The CMD180 is fully characterized and guaranteed over the industrial/military temperature range of –40 °C to +85 °C. This specification is validated per Qorvo's qualified test flow and applies to all key RF parameters-including gain, noise figure, and OIP3-ensuring reliable operation in outdoor radar housings and avionics environments where thermal cycling occurs.
Does the CMD180 require external DC blocking capacitors at RF_IN or RF_OUT?
No, the CMD180 integrates on-chip DC blocking capacitors at both RF_IN (Pin 5) and RF_OUT (Pin 12). This eliminates the need for external series capacitors, reduces PCB footprint, and improves broadband impedance repeatability-especially critical in multi-GHz receiver designs where capacitor parasitics degrade match.
What is the recommended PCB layout practice for the CMD180's exposed paddle?
The CMD180's exposed paddle must be soldered to a solid, low-impedance thermal/RF ground plane using ≥90% solder coverage and thermal vias spaced ≤1 mm apart. This ensures effective heat dissipation (TJ rise <15 °C at 60 mA) and maintains RF stability by minimizing ground inductance-critical for achieving specified noise and linearity performance.
Is the CMD180 pin-compatible with any other Qorvo LNA in the same package?
No, the CMD180 has a unique pin assignment optimized for its internal bias architecture and RF routing. While other Qorvo QFN LNAs (e.g., CMD178, CMD203) share the 3 mm × 3 mm 16-pin QFN outline, their pin functions-including VDD, RF_IN, RF_OUT, and GND locations-differ. Direct replacement requires PCB redesign and layout verification.
How does the CMD180's integrated bias network simplify system design?
The CMD180's integrated bias network provides stable gate voltage and drain current without external resistors or decoupling networks. This reduces bill-of-materials count by up to four passive components per device, eliminates gate bias tuning during production, and improves long-term reliability-particularly valuable in high-volume radar sensor modules where assembly yield and test time impact cost.
