Analog Devices Inc. HMC607

Overview

HMC607G7 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC SPDT switch optimized for RF signal routing in DC–6 GHz systems. It delivers 1.9 dB typical insertion loss at 6 GHz, >42 dB isolation up to 6 GHz, and operates with -5/0 V complementary logic control-no external bias supply required. Its non-reflective design and hermetic SMT package support high-reliability telecom and defense front-end modules.

For engineers reviewing the HMC607G7 datasheet, HMC607G7 pinout, HMC607G7 application, or HMC607G7 equivalent, key selection criteria include isolation vs. frequency trade-offs, -5/0 V control compatibility, DC-coupled 50 Ω RF ports requiring external blocking capacitors, and thermal resistance of 94 °C/W for power-handling validation in compact RF layouts.

Technical Context

The HMC607G7 implements a GaAs MESFET-based non-reflective SPDT architecture with complementary negative-voltage control (A/B pins), enabling simultaneous ON/OFF path termination to 50 Ω. Its DC-coupled RF ports (RF1, RF2, RFC) require external DC blocking capacitors when interfacing with biased signal chains.

Switching is characterized by 3 ns tRISE/tFALL and 6 ns tON/tOFF across DC–6 GHz, with specified operation from -40 °C to +85 °C and absolute max RF input power of +30 dBm at +50 °C. The device uses a hermetic ceramic package with gold-plated Kovar leads and requires full ground paddle soldering per RF layout best practices.

FAQ

What control voltage levels does the HMC607G7 require?

The HMC607G7 requires complementary negative control voltages: logic HIGH is -5 V (typical, up to -7 V), and logic LOW is 0 to -0.2 V. No positive supply or bias rail is needed. This matches legacy military and telecom systems using negative logic families. The HMC607G7 truth table defines RFC→RF1 and RFC→RF2 states based on A and B pin combinations, and all control pins draw ≤45 µA.

Does the HMC607G7 require external DC blocking capacitors?

Yes, the HMC607G7 RF ports (RF1, RF2, RFC) are DC-coupled and internally matched to 50 Ω. External DC blocking capacitors must be placed in series with each RF port if the connected circuitry has non-zero DC potential. Failure to do so may cause unintended biasing, degraded return loss, or damage. The HMC607G7 datasheet specifies this requirement explicitly in the Pin Descriptions section.

What is the maximum RF input power rating for the HMC607G7?

The HMC607G7 supports +30 dBm RF input power at +50 °C ambient, with an absolute maximum channel temperature of 150 °C. At +25 °C, its 1 dB compression point is +27 dBm (0.5–6 GHz). Derating is required above +50 °C per its thermal resistance of 94 °C/W. The HMC607G7 must not be hot-switched above +27 dBm to avoid reliability risk.

Is the HMC607G7 pin-compatible with the Skyworks AS406M2-10?

No, the HMC607G7 is not pin-compatible with the Skyworks AS406M2-10. While both are non-reflective GaAs SPDT switches with -5/0 V control, the HMC607G7 uses a 7-lead ceramic package with dedicated A/B control pairs and shared ground paddle, whereas the AS406M2-10 uses a different lead count, pin assignment, and package outline. Layout redesign is required for substitution.

What is the operating temperature range for the HMC607G7?

The HMC607G7 is specified for continuous operation from -40 °C to +85 °C ambient. Its hermetic ceramic package and GaAs die enable reliable performance across this full industrial/military range. Storage temperature extends to -65 °C to +150 °C. The HMC607G7 electrical specifications-including isolation, insertion loss, and switching time-are guaranteed only within the -40 °C to +85 °C operating range.
