Product details
Overview
HMC-C071 from Analog Devices is a GaAs MMIC SP4T non-reflective switch operating from DC to 20 GHz, delivering 2.8 dB insertion loss at 12 GHz, >42 dB isolation up to 12 GHz, and 17 ns rise/fall times. It uses a +5 V CMOS-compatible control interface and is housed in a hermetic C-15 module with field-replaceable SMA connectors for microwave radio and test instrumentation signal routing.
For engineers reviewing the HMC-C071 datasheet, HMC-C071 pinout, HMC-C071 application, or HMC-C071 equivalent, key selection criteria include broadband isolation performance across 0.5–20 GHz, non-reflective RF path behavior under all switch states, DC-coupled 50 Ω SMA ports requiring external DC blocking, and operation over –55 °C to +85 °C without thermal derating.
Technical Context
The HMC-C071 implements a monolithic GaAs pHEMT-based SP4T architecture with four independent RF paths (RFC→RF1/RF2/RF3/RF4) controlled by two CMOS-level digital inputs (Vctl1/Vctl2). Its non-reflective design terminates off-state ports into 50 Ω, minimizing VSWR impact on source impedance.
It operates with a single +5 V bias (1.4 mA typical quiescent current), supports TTL/CMOS logic thresholds (0–1.5 V low, +3–+5 V high), and maintains specified RF performance across –55 °C to +85 °C ambient without external compensation circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 20 GHz - enables full-band coverage from baseband through K-band without band switching. |
| Insertion Loss | 2.8 dB @ 12 GHz - limits signal attenuation in high-frequency transmit/receive paths. |
| Isolation | >42 dB @ ≤12 GHz - suppresses crosstalk between active and inactive RF paths in multi-channel systems. |
| Rise/Fall Time | 17 ns - supports fast time-domain switching in pulsed radar and TDD-based communication systems. |
| P1dB | 24 dBm @ 20 GHz - defines maximum linear input power before 1 dB gain compression occurs. |
| IP3 | 40 dBm @ 20 GHz - indicates strong linearity for handling two-tone interference in wideband receivers. |
| Operating Temp | –55 °C to +85 °C - ensures reliability in military, aerospace, and outdoor telecom environments. |
Pinout & Package
Package: Hermetic C-15 module with gold-plated Kovar housing and field-replaceable SMA female connectors (RFC, RF1–RF4); 5-pin control interface with ground, dual control lines, and +5 V supply.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power supply reference ground - must be low-inductance connected to system chassis ground. |
| 2, 3 | Vctl1, Vctl2 | CMOS control inputs - require active pull-up to +5 V; logic state selects RFC→RF1/RF2/RF3/RF4 path. |
| 4 | Vdc | +5 V DC supply input - delivers 1.4 mA typical bias current; tolerant of ±10% variation. |
| 5–9 | RFC, RF1, RF2, RF3, RF4 | DC-coupled 50 Ω SMA ports - RFC is common port; RF1–RF4 are selectable outputs; DC blocking required if external DC potential ≠ 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Non-reflective topology | Terminates off-state ports into 50 Ω, maintaining stable source match regardless of switch state - critical for cascaded amplifier stages. |
| Hermetic C-15 packaging | Sealed Kovar enclosure with gold plating ensures long-term reliability in humid, corrosive, or vacuum environments. |
| Field-replaceable SMA connectors | Enables connector maintenance without rework of internal MMIC - reduces lifecycle cost in test instrumentation deployments. |
| CMOS-compatible control | Accepts standard 0/+5 V logic levels with <20 µA low-state leakage - simplifies integration with FPGA/CPLD GPIOs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SP4T RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC-C070 | Same C-15 package and pinout; reflective (not non-reflective) architecture; 35 dB isolation @ 20 GHz vs. 32 dB for HMC-C071. | Limited to applications where off-state VSWR is managed externally; unsuitable for amplifier output switching. | Select HMC-C070 only when cost sensitivity outweighs need for non-reflective termination and system-level match stability. |
| Qorvo QM11036 | SP4T GaAs pHEMT switch in 5×5 mm QFN; 3.2 dB IL @ 12 GHz; 30 dB isolation @ 20 GHz; requires external 50 Ω terminations for non-reflective behavior. | Surface-mount solution for PCB-integrated designs; lacks field-replaceable connectors and hermetic sealing. | Choose QM11036 for space-constrained, high-volume production where connector serviceability is not required. |
Compared with HMC-C070 and QM11036, the HMC-C071 uniquely combines hermetic C-15 packaging, true non-reflective operation, and field-replaceable SMA connectors - making it the only option qualified for ruggedized test equipment and military platform front-ends requiring zero downtime for connector replacement.

FAQ
What is the operating voltage requirement for the HMC-C071?
The HMC-C071 requires a single +5 V DC supply (Vdc) with ±10% tolerance, drawing 1.4 mA typical quiescent current. Control inputs (Vctl1/Vctl2) accept CMOS logic levels: low state = 0–1.5 V (<20 µA leakage), high state = +3.0 V to +5.0 V (<1 mA). Exceeding +7 V on Vdc violates absolute maximum ratings.
Does the HMC-C071 require external DC blocking capacitors?
Yes, the HMC-C071 RF ports (RFC, RF1–RF4) are DC-coupled and matched to 50 Ω. External DC blocking capacitors must be placed in series with each RF line if the connected circuit's DC potential differs from 0 V, preventing bias disruption or damage to the internal GaAs pHEMT devices.
What is the meaning of "non-reflective" in the HMC-C071 datasheet?
"Non-reflective" means the HMC-C071 internally terminates all off-state RF ports into 50 Ω, ensuring stable 50 Ω input/output impedance regardless of switch state. This eliminates VSWR degradation in cascaded stages - unlike reflective switches, which present open or shorted impedances when off, risking amplifier instability.
Can the HMC-C071 be used above 20 GHz?
No, the HMC-C071 is characterized and guaranteed from DC to 20 GHz. Insertion loss exceeds –5 dB and isolation falls below 32 dB beyond 20 GHz per datasheet specifications. Operation above 20 GHz is outside rated performance and not supported by Analog Devices' characterization data for the HMC-C071.
What is the thermal operating range of the HMC-C071?
The HMC-C071 operates reliably from –55 °C to +85 °C ambient temperature, with full RF specifications maintained across this range. The hermetic C-15 package enables stable performance in uncontrolled environments such as airborne radar housings or outdoor telecom cabinets without additional thermal management.
