Product details
Overview
HMC190AMS8E from Hittite Microwave Corporation is a GaAs MMIC SPDT switch in MSOP-8 package, delivering 0.4 dB insertion loss at DC–1.0 GHz, +50 dBm input IP3, and 27 dB isolation at DC–1.0 GHz for RF signal routing in portable wireless transceivers operating at 0.9/1.9/2.4 GHz.
For engineers reviewing the HMC190AMS8E datasheet, HMC190AMS8E pinout, HMC190AMS8E application, or HMC190AMS8E equivalent, key selection criteria include positive-control voltage compatibility (0/+3 V to 0/+8 V), ultra-low control current (≤5 µA), DC–3 GHz bandwidth, and RoHS-compliant matte Sn lead finish with MSL1 rating.
Technical Context
This GaAs MMIC switch uses monolithic integration to implement a single-pole double-throw topology with two independent control inputs (A/B) enabling bidirectional RF path selection. It operates with positive logic only-no negative voltage required-and maintains VSWR <1.2:1 up to 2 GHz.
The device employs direct-coupled GaAs FET architecture optimized for low distortion and fast switching: tRISE/tFALL = 3 ns, tON/tOFF = 10 ns, and supports DC blocking at all three RF ports (RFC, RF1, RF2) per design requirement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC239S8 | Negative control (−3 V / 0 V); same GaAs MMIC process and RF specs; requires level-shifting circuitry | Used where legacy designs mandate negative logic; not drop-in compatible due to inverted control polarity | Select HMC239S8 only if existing control logic supplies −3 V and ground, avoiding redesign of driver stage |
| Qorvo QM11036 | 0.1–6.0 GHz range; higher P1dB (+34 dBm); 10-lead QFN package; requires different PCB layout and thermal management | Targeted at 5G NR sub-6 GHz base stations needing wider bandwidth and higher power handling | Choose QM11036 when extending beyond 3 GHz or requiring >+30 dBm P1dB; not suitable for space-constrained portable designs |
Compared with HMC239S8 and QM11036, the HMC190AMS8E offers optimal balance of ultra-low control current, MSOP-8 compactness, and verified DC–3 GHz performance for cost-sensitive portable wireless systems-without requiring level shifters or board re-layout.

FAQ
What is the maximum RF input power the HMC190AMS8E can handle without damage?
The HMC190AMS8E has absolute maximum ratings specifying +34 dBm input power for 0.5–2 GHz when VCTL = 0/+8 Vdc. Operation above +20 dBm during switching ("hot switching") is prohibited to avoid reliability degradation. For continuous wave operation, the 1 dB compression point reaches +31 dBm at 1900 MHz with 0/+5 V control, making the HMC190AMS8E suitable for medium-power portable radio front-ends but not high-power base station applications.
Does the HMC190AMS8E require external DC blocking capacitors?
Yes, the HMC190AMS8E requires external DC blocking capacitors at RFC, RF1, and RF2 ports as stated in the datasheet caution notes. This is mandatory because the device lacks internal DC blocking; failure to install them risks bias disruption and potential damage from DC offset. Typical values are 330 pF in 0402 package, with cutoff frequency determined by capacitor value and system impedance.
Can the HMC190AMS8E be used with 0/+3 V control logic without level shifting?
Yes, the HMC190AMS8E is explicitly designed for positive-only control and fully supports 0/+3 V logic levels per its truth table and electrical specifications. Control inputs A and B draw ≤3 µA at 0/+3 V, enabling direct connection to microcontroller GPIOs or HC-series logic gates without level shifters-making it ideal for low-voltage battery-powered systems like Bluetooth/Wi-Fi modules.
What is the thermal and moisture sensitivity classification of the HMC190AMS8E?
The HMC190AMS8E carries an MSL1 (Moisture Sensitivity Level 1) rating per JEDEC J-STD-020, indicating unlimited floor life at ≤30 °C/60% RH. Its RoHS-compliant matte Sn finish supports peak reflow temperatures up to 260 °C, and the package uses low-stress injection-molded plastic to minimize thermal stress during assembly-critical for high-yield manufacturing of compact RF modules.
How does the HMC190AMS8E compare to the HMC190AMS8 in terms of material composition and assembly compatibility?
The HMC190AMS8E differs from the HMC190AMS8 solely in lead finish and RoHS compliance: HMC190AMS8E uses 100% matte Sn with max reflow at 260 °C, while HMC190AMS8 uses Sn/Pb solder with max reflow at 235 °C. Both share identical electrical specs, pinout, MSOP-8 package dimensions, and marking "H190A". The HMC190AMS8E is backward-compatible in assembly but requires lead-free reflow profile adjustment.
