Product details
Overview
HMC986-SX from Analog Devices (formerly Hittite Microwave) is a GaAs pHEMT MMIC reflective SPDT switch die operating from 0.1 to 50 GHz, delivering 1.9 dB insertion loss and 31 dB isolation at 40 GHz with 0/-3V to 0/-5V complementary control, designed for RF signal routing in high-frequency test equipment and EW subsystems.
For engineers reviewing the HMC986-SX datasheet, HMC986-SX pinout, HMC986-SX application, or HMC986-SX equivalent, this page provides verified wideband RF switch specifications, die-level package mapping, truth-table–driven control behavior, and application-specific performance data across temperature and bias conditions.
Technical Context
The HMC986-SX implements a reflective SPDT topology using GaAs pHEMT process technology, enabling broadband operation without external matching components. Its complementary control inputs (V1/V2) drive two independent switch paths-RFC↔RF1 and RFC↔RF2-with no DC path between RF ports.
RF performance remains stable across -3V and -5V control voltage ranges, with return loss ≥20 dB over full 0.1–50 GHz band in "on" state. Switching is characterized by 10 ns tON/tOFF and 1 ns tRISE/tFALL, supporting high-speed reconfiguration in radar T/R modules and switching matrices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.1–50 GHz continuous band: supports single-device coverage from HF through W-band without band-switching. |
| Insertion Loss | 1.9 dB at 40 GHz: enables low-loss signal routing in millimeter-wave test fixtures and ECM front-ends. |
| Isolation | 31 dB at 40 GHz: prevents cross-coupling between active and terminated RF paths in multi-channel systems. |
| Switching Speed | 10 ns tON/tOFF: allows sub-100 MHz reconfiguration rates for agile frequency-hopping or beam-steering control. |
| Control Voltage | 0/-3V to 0/-5V complementary logic: compatible with standard negative-voltage GaAs driver ICs and avoids level-shifting circuitry. |
| Die Size | 0.98 × 0.75 × 0.1 mm: fits compact RF module layouts and enables dense integration in phased-array tile assemblies. |
| Operating Temp | -55°C to +85°C: qualified for military comms, airborne radar, and ground-based EW platforms with extended thermal cycling. |
Pinout & Package
Package: Bare die in WP-13 waffle pack; 0.102 mm (4 mil) thick GaAs substrate with gold backside metallization (grounded); overall dimensions 0.98 × 0.75 mm ±0.05 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RF1, RFC, RF2 | RF signal ports | DC-coupled 50 Ω matched ports; require external blocking capacitors if DC potential differs from 0 V; measured with GSG interface. |
| V1, V2 | Complementary control inputs | V1 high + V2 low selects RFC→RF1; V1 low + V2 high selects RFC→RF2; both high/low states are invalid per truth table. |
| Pads 1,3,4,6,7,9 | RF signal grounds | Connected to backside ground; used for Ground-Signal-Ground (GSG) RF interconnect to minimize parasitic inductance. |
| Pads 10,13 | Control signal ground returns | Optional ground returns for V1/V2 bias lines; improve control signal integrity in high-speed switching applications. |
Key Features
| Feature | Design Value |
|---|---|
| Reflective SPDT architecture | Eliminates need for external termination resistors on "off" port, reducing board area and insertion loss in compact RF modules. |
| Wideband 0.1–50 GHz operation | Single device replaces multiple narrowband switches in broadband instrumentation, lowering BOM count and calibration complexity. |
| 1.9 dB insertion loss @ 40 GHz | Preserves signal-to-noise ratio in receiver front-ends and maintains output power efficiency in transmitter switching paths. |
| 31 dB isolation @ 40 GHz | Enables simultaneous transmit/receive (T/R) isolation in radar duplexers without additional circulators or filters. |
| 10 ns switching speed | Supports real-time channel selection in electronic warfare jamming waveforms and fast-scan test system architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband reflective SPDT switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1087-SX | Same GaAs pHEMT process, 0.1–40 GHz range, 2.1 dB IL @ 40 GHz, 28 dB isolation @ 40 GHz. | Narrower upper frequency limit; lower isolation limits use in high-dynamic-range EW receivers. | Select when 40 GHz max frequency suffices and cost optimization is prioritized over W-band extension. |
| Qorvo QM11036 | GaAs pHEMT SPDT, 0.05–40 GHz, 2.3 dB IL @ 40 GHz, 26 dB isolation @ 40 GHz, +5 V/0 V control. | Positive-control interface requires level-shifting; 4 dB higher IL and 5 dB lower isolation than HMC986-SX at 40 GHz. | Choose for +5 V logic compatibility where W-band coverage and ultra-low loss are noncritical. |
Compared with HMC1087-SX and QM11036, the HMC986-SX uniquely extends usable bandwidth to 50 GHz while maintaining <2 dB insertion loss and >30 dB isolation-critical for next-generation test systems and W-band radar/EW hardware where spectral purity and path loss directly impact system noise figure and jamming effectiveness.

FAQ
What is the control voltage requirement for reliable operation of the HMC986-SX?
The HMC986-SX requires complementary control voltages of 0 V (low) and -3 V to -5 V (high) applied to V1 and V2 pins. Both inputs must be driven within this range; operation outside ±0.2 V for low and beyond -5.5 V for high violates absolute maximum ratings. The HMC986-SX exhibits identical RF performance at both -3 V and -5 V high states, allowing flexibility in driver IC selection without recalibration.
Does the HMC986-SX require external DC blocking capacitors on its RF ports?
Yes, the HMC986-SX RF ports (RF1, RFC, RF2) are DC-coupled and internally matched to 50 Ω, so external DC blocking capacitors are mandatory if the connected RF transmission line carries non-zero DC potential. The HMC986-SX datasheet measurements were performed using Ground-Signal-Ground (GSG) probe interfaces with proper DC blocking, and omitting them risks bias disruption and degraded return loss.
What is the maximum RF input power the HMC986-SX can handle at 40 GHz?
At 40 GHz, the HMC986-SX supports +25 dBm input power for 0.1 dB compression and +10 dBm for 1.0 dB compression under -5 V control. These values are specified for continuous-wave (CW) signals; pulsed operation may allow higher peak power depending on duty cycle and thermal management. The HMC986-SX hot-switch power rating at 40 GHz is +23 dBm, defining safe reconfiguration under RF load.
How is the HMC986-SX packaged and what handling precautions apply?
The HMC986-SX is supplied as a bare die in WP-13 waffle pack, with gold backside metallization grounded to the PCB. It is an electrostatic-sensitive device (ESD): handling requires nitrogen storage after opening, vacuum collet edge-only pickup, and avoidance of surface contact due to fragile air bridges. The HMC986-SX must be mounted eutectically or with conductive epoxy onto a grounded plane, and wirebonded using 1-mil gold wire with strict bond length <12 mils.
Can the HMC986-SX be used in a series-switch configuration?
No-the HMC986-SX is a reflective SPDT switch, meaning its "off" port presents a high-impedance (open-circuit) termination rather than a series-connected path. It is not designed for in-line insertion; attempting series use causes severe mismatch and return loss degradation. The HMC986-SX must be used in shunt/reflective topologies, such as RFC-to-RF1/RF2 routing, as validated in its functional diagram and application schematics.
