Product details
Overview
HMC190AMS8 from Hittite Microwave Corporation is a GaAs MMIC SPDT switch operating from DC to 3 GHz, featuring 0.4 dB typical insertion loss at 1 GHz, +50 dBm input IP3, and positive control logic (0/+3 V, 3 µA). It is used in RF front-end signal routing for portable wireless transceivers and MMDS/WirelessLAN systems.
For engineers reviewing the HMC190AMS8 datasheet, HMC190AMS8 pinout, HMC190AMS8 application, or HMC190AMS8 equivalent, key selection criteria include its MSOP8 package compatibility, DC–3 GHz bandwidth, low control current, high linearity (+50 dBm IP3), and VSWR <1.2:1 up to 2 GHz - all critical for battery-powered 0.9/1.9/2.4 GHz radio designs.
Technical Context
The HMC190AMS8 implements a monolithic GaAs MMIC architecture with two independent control inputs (A/B) enabling bidirectional SPDT switching via complementary positive-voltage logic (e.g., 0/+3 V or 0/+5 V). Its design integrates on-chip bias networks and optimized impedance matching for 50 Ω RF paths.
It delivers stable RF performance across -40°C to +85°C with MSL1 moisture sensitivity rating, requires DC blocking capacitors at RFC, RF1, and RF2 ports, and supports hot-switching only up to +20 dBm (Vctl = +5 Vdc) per absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 3 GHz - enables broadband RF signal routing without band-select filtering. |
| Insertion Loss (1 GHz) | 0.4 dB typ - minimizes path loss in transmit/receive chains, preserving SNR in low-power radios. |
| Input IP3 | +50 dBm @ 0.5–3 GHz - ensures high linearity for multi-tone signals in WLAN/MMDS base stations. |
| Isolation (1 GHz) | 27 dB typ - suppresses crosstalk between RF1 and RF2 paths during switching. |
| Control Voltage | 0/+3 V or 0/+5 V - compatible with standard CMOS/TTL logic interfaces without level-shifting. |
| Switching Time | 3 ns tRISE/tFALL - supports fast TDD mode transitions in time-division duplex systems. |
| VSWR (≤2 GHz) | <1.2:1 - reduces mismatch loss and improves return loss stability across UHF/L-band. |
Pinout & Package
Package: 8-lead MSOP (Moisture Sensitivity Level 1, Sn/Pb lead finish, low-stress molded plastic body).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Control Input A | Positive logic enable for RF→RF1 path; 0 V selects RF1, +3/+5 V deselects RF1. |
| 2 (GND) | Ground | RF and DC ground reference; must be soldered directly to PCB ground plane. |
| 3 (RF1) | RF Output 1 | 50 Ω matched RF port; requires external DC blocking capacitor. |
| 4 (GND) | Ground | Secondary RF ground; connects to same ground plane as Pin 2. |
| 5 (RFC) | RF Common | 50 Ω matched RF input; shared path for both switched outputs. |
| 6 (GND) | Ground | Third ground terminal; mandatory connection for thermal and RF stability. |
| 7 (RF2) | RF Output 2 | 50 Ω matched RF port; requires external DC blocking capacitor. |
| 8 (B) | Control Input B | Positive logic enable for RF→RF2 path; complements Pin 1 (e.g., A=0 V, B=+3 V → RF→RF2). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low control current | 3 µA per control input - extends battery life in portable 0.9/1.9/2.4 GHz radios. |
| High input linearity | +50 dBm IIP3 - maintains signal fidelity under multi-carrier conditions in WirelessLAN. |
| Small-footprint packaging | MSOP8 (3.0 × 3.0 mm) - saves board space in compact RF modules and handheld devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC239S8 | Negative control logic (−3 V/+3 V), same GaAs MMIC process and RF specs. | Requires negative voltage rail; not drop-in compatible with HMC190AMS8's positive-only control interface. | Select when system already provides −3 V bias and needs identical RF performance with inverted logic polarity. |
| Qorvo QM11036 | 0.1–6.0 GHz range, 0.5 dB IL @ 2.4 GHz, +47 dBm IP3, 1.8–5.5 V control. | Broadband coverage beyond 3 GHz; higher control voltage flexibility but slightly lower linearity. | Prefer for multi-band IoT gateways needing 5 GHz Wi-Fi support and single-supply 3.3 V logic compatibility. |
Compared with HMC239S8 and QM11036, the HMC190AMS8 offers the lowest insertion loss (0.4 dB) and highest IP3 (+50 dBm) within its DC–3 GHz range, while requiring only positive control voltages - making it optimal for cost-sensitive, battery-powered 0.9/1.9/2.4 GHz radios where power efficiency and linearity are prioritized over ultra-wideband coverage.

FAQ
What is the maximum RF input power the HMC190AMS8 can handle without compression?
The HMC190AMS8 delivers 1 dB compression at +30 dBm (typ) for 0.5–1.0 GHz and +29 dBm (typ) for 0.5–3.0 GHz when Vctl = 0/+5 V. Absolute maximum input power is +34 dBm (0.5–2 GHz) per absolute ratings, but operation above +31 dBm at Vctl = +5 Vdc is cautioned against to avoid reliability degradation. Always refer to the HMC190AMS8 datasheet for derating curves versus control voltage and frequency.
Does the HMC190AMS8 require external DC blocking capacitors?
Yes, the HMC190AMS8 requires external DC blocking capacitors at RFC, RF1, and RF2 ports, as stated in the datasheet caution notes and typical application circuit. These capacitors prevent DC bias from interfering with connected components and define the low-frequency cutoff - value selection determines operational lower limit (e.g., 330 pF supports ~100 MHz minimum).
What is the recommended PCB grounding practice for the HMC190AMS8?
All ground pins (Pins 2, 4, 6) and the exposed package bottom must be soldered directly to a solid RF ground plane, per the outline drawing notes and evaluation board guidelines. This ensures thermal dissipation, minimizes inductance in RF return paths, and maintains VSWR <1.2:1 up to 2 GHz - critical for repeatable RF performance in production layouts.
Can the HMC190AMS8 operate with 0/+8 V control logic?
Yes, the HMC190AMS8 supports control voltages up to +8 Vdc per absolute maximum ratings and truth table data. At 0/+8 V, it achieves +34 dBm input P1dB and +52 dBm IP3 at 900 MHz, but control current rises to ±32 µA. System designers must verify logic driver capability and ensure no exceedance of ±0.2 Vdc tolerance on control inputs.
Is the HMC190AMS8 pin-compatible with the HMC190AMS8E variant?
Yes, the HMC190AMS8 and HMC190AMS8E share identical pinout, electrical specifications, and MSOP8 package dimensions. The sole difference is RoHS compliance: HMC190AMS8E uses 100% matte Sn lead finish and 260 °C peak reflow, while HMC190AMS8 uses Sn/Pb and 235 °C peak reflow. Both are functionally interchangeable in new designs where lead-free compliance is required.
