Product details
Overview
HMC-C019 from Analog Devices (formerly Hittite Microwave) is a hermetically sealed GaAs MESFET SPST RF switch module with field-replaceable SMA connectors, delivering 100 dB isolation up to 4 GHz and 65 dB up to 20 GHz, 3.5 dB insertion loss at 10 GHz, and sub-10 ns switching times for high-speed pulse modulation in microwave test instrumentation.
For engineers reviewing the HMC-C019 datasheet, HMC-C019 pinout, HMC-C019 application, or HMC-C019 equivalent, key selection criteria include DC–20 GHz bandwidth, non-reflective topology, CMOS-compatible +5 V control interface, -55 °C to +85 °C operating range, and hermetic C-9 package with SMA connectivity.
Technical Context
The HMC-C019 implements a non-reflective SPST topology using GaAs MESFETs, enabling simultaneous RF path termination in both ON and OFF states to minimize system-level signal reflections. Its CMOS-compatible control interface accepts 0/+5 V logic with <1 mA typical bias current per control line.
DC-coupled RF ports require external DC blocking capacitors when interfacing with biased signal lines. Switching transients are limited to 20 mVpp across DC–20 GHz, supporting clean RF pulse shaping in radar and ECM systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 20 GHz - supports broadband microwave signal routing without band segmentation. |
| Isolation | 100 dB @ ≤4 GHz, 65 dB @ ≤20 GHz - enables high-dynamic-range signal separation in multi-path test setups. |
| Insertion Loss | 3.5 dB @ 10 GHz - preserves RF signal amplitude integrity in high-frequency receiver front-ends. |
| Switching Speed | tON/tOFF = 8.5 ns - allows ≥100 MHz pulse repetition rates for fast RF gating applications. |
| Operating Temp | -55 °C to +85 °C - qualified for deployment in military radios, radar subsystems, and outdoor telecom infrastructure. |
| Control Interface | +5 V CMOS - simplifies integration with FPGA/CPLD-based timing controllers without level-shifting circuitry. |
| P1dB Compression | 23 dBm @ 0.5–20 GHz - handles moderate-power RF signals without gain compression in VSAT transmit chains. |
Pinout & Package
The HMC-C019 is housed in a hermetic C-9 package (Kovar body, gold-plated finish) measuring 1.00" × 0.75" × 0.35", with integrated field-replaceable SMA female connectors and mounting spacers (P/N 111532).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | RF1, RF2 | DC-coupled 50 Ω RF I/O ports; require external DC blocking if connected to biased signal paths. |
| 2, 6 | GND | Power supply ground reference for bias and control circuits; must be low-inductance connection. |
| 3, 7 | Vctl1, Vctl2 | CMOS control inputs; active pull-up to +5 V required; logic high = RF path enabled. |
| 4, 8 | Vdc1, Vdc2 | +5 V ±10% bias supply inputs; 2.8 mA typical quiescent current per rail. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1082LP4E | Same manufacturer, GaAs pHEMT, 0.1–40 GHz, 4.5 dB IL @ 20 GHz, 55 dB isolation @ 20 GHz, QFN-24 package. | Surface-mount, no SMA connectors; requires RF layout integration and external matching. | Preferred for compact PCB-integrated designs where connectorization is handled externally. |
| Qorvo QM11036 | 0.01–20 GHz, 3.2 dB IL @ 10 GHz, 60 dB isolation @ 20 GHz, 5 V CMOS control, 4 mm × 4 mm DFN. | Non-hermetic plastic package; rated for -40 °C to +85 °C only; no field-replaceable connectors. | Suitable for cost-sensitive commercial telecom modules where environmental ruggedness is secondary. |
Compared with HMC-C019, HMC1082LP4E offers wider bandwidth but sacrifices connector convenience and hermeticity, while QM11036 reduces size and cost but lacks field-serviceability and extended temperature capability-making HMC-C019 optimal for lab, defense, and infrastructure applications demanding reliability and modularity.

FAQ
What is the RF port configuration of the HMC-C019?
The HMC-C019 is a single-pole single-throw (SPST) switch with two DC-coupled 50 Ω RF ports (RF1 and RF2), each implemented as an SMA female connector. In the ON state, RF1 connects to RF2; in the OFF state, both ports are terminated to 50 Ω, maintaining non-reflective behavior. The HMC-C019 does not support SPDT or multiplexed configurations.
Does the HMC-C019 require external DC blocking capacitors?
Yes, the HMC-C019 RF ports are DC-coupled and require external DC blocking capacitors when interfacing with signal sources or loads that have non-zero DC potential. This prevents unintended bias injection into connected components and ensures proper RF termination. The HMC-C019 itself contains no internal DC blocking.
What is the maximum RF input power the HMC-C019 can handle continuously?
The HMC-C019 has an absolute maximum RF input power rating of +27 dBm and a hot-switch power limit of +23 dBm. For continuous operation without degradation, the recommended maximum is +23 dBm across 0.5–20 GHz, aligning with its P1dB compression point. Exceeding this risks permanent damage or parametric shift.
Can the HMC-C019 operate outside the specified -55 °C to +85 °C range?
No-the HMC-C019 is characterized and guaranteed only from -55 °C to +85 °C. While storage temperature extends to -65 °C to +150 °C, operation outside the specified range may cause parametric drift, increased insertion loss, reduced isolation, or irreversible failure. The HMC-C019 must be used within its rated operating temperature window.
How are the control pins Vctl1 and Vctl2 used in the HMC-C019?
Vctl1 and Vctl2 are CMOS-compatible control inputs requiring active pull-up to +5 V. A logic high (+3.5 V to +5 V) enables the RF path (ON); a logic low (0 to +1.5 V) disables it (OFF). Both pins must be driven simultaneously-no differential or complementary signaling is supported. The HMC-C019 does not interpret independent control of Vctl1 and Vctl2.
